PTT Bulletin Board System

Using the TELNET protocol, PTT provides a quick, free of charge, and open online forum community. Currently, PTT has two branch sites, PTT2 (批踢踢兔) and PTT3 (批踢踢參). Of the three sites, the main site PTT[5] is largest in scale and capacity, currently handling up to 150,215 visitors online at a time (9 September 2008), making it the largest Chinese language-based BBS in the world.

The main site was founded on 9 September 1995 by Yi-Chin Tu (杜奕瑾 Dù Yìjǐn), then a sophomore in the Department of Computer Science and Information Engineering at National Taiwan University. PTT2 was founded in 2000, with the aim of providing a similar system centered around groups and individuals. PTT3, powered by MediaWiki, was founded in 2004 in Washington, D.C., United States for Taiwanese students studying abroad. PTT also provides wiki and blog services for registered users. The PTTwiki service was activated on 5 February 2004 and powered by Tavi wiki system. It is the main wiki service for individuals in Taiwan.

Since 2000, PTT has become the largest online forum in Taiwan due to its increasing number of users. Various issues are enthusiastically discussed on PTT, even to a profound extent generating social impacts in reality. The newspaper and television media started to report on PTT, with journalists assigned to monitor PTT for the latest updates.

PTT is registered as a student organization at the National Taiwan University. The BBS Technology Research Club (臺大 BBS 研究社) was founded in 1999 by several BBS sites at NTU, with Yi-Chin Tu as its leader. In 1999 and 2000, the club held public events on campus for BBS users.

Although PTT is a club and the most famous BBS site in Taiwan, it is not the official BBS site for NTU. The machines and other hardware used to set up PTT was obtained by the administrators without the help of the university, and hence it operates with a high level of freedom. However, it still operates on the NTU network, and hence must abide by its rules and regulations.

PTT runs under Linux, while PTT2 runs under FreeBSD 4.11. The BBS system used by PTT, PTT2, PTT3 is called Open PTT, and is under the GPL.

The code for PTT was originally forked from MapleBBS 2.36 that operated the Sun of Beach BBS. Many programmers and system administrators contributed to the PTT project, with the goals of making PTT efficient in terms for memory usage and disk access and allowing as many users on the system at a single time as possible. The code is licensed under GPL 2.0.

The forums are subdivided into boards (看板 pinyin：Kànbǎn, noticeboard or bulletinboard) and named by a string of alphanumeric characters. These boards can be searched as well as ordered by popularity. They can also be added to a user's list of favorite boards.

As PTT is a liberal platform for public opinions, it allows netizens to access and comment on social matters easily, including news or specific persons, based on their personal perspective and/or agenda. However, since netizens on PTT do not need to disclose their real names while citing news or publishing their opinions, some netizens abuse their status of anonymity and make undesirable comments. PTT, therefore, is easily used for publishing fake news and for inciting cyberbullying. The death of Cindy Yang (楊又穎) is an occurrence of this, and it is the first time netizens in PTT were made aware of this issue. Cindy Yang, a model and actress, committed suicide in 2015, after suffering from taunts and accusations from various social media, notably PTT. The news about Yang's suicide triggered a heated discussion. Some netizens began to self-examine the bullying culture in PTT. The targets of bullying in PTT are often celebrities and politicians, as well as their families. The most notorious example might be the bullying of Chen Hsing-Yu (陳幸妤), daughter of a former president. She and her boyfriend's (now husband's) relationship became the cover story of the first issue of The Next Magazine. Subsequently, corruption incidents attributed to her father, and insider trading allegations against her partner were leveraged for harassment by users of PTT for several years. Additionally, in 2017, the Islamic Association of Taiwan publicly criticized PTT allowing the users to spread fake news and post hate speech about Muslims, and calling it names such as “garbage religion” or “Muslims are trash” thus the Islamic Association of Taiwan protested against the government to voice concern about abuse of anonymity in PTT. Much of the fake news is copied and recycled by tabloids and even mainstream media and causes foreign media to be confused in particular during election times.

Moreover, anonymity led to more irrational and extreme behavior in other aspects. For example, in 2009, Dell Computer has mispriced its LCD monitor and notebook products on its official website and this aroused lots of netizens on PTT to go fishing for cheap deals. They mobilized ten and thousands of netizens to order the mispriced items and ordered Dell computer to sell its products at a fraction of its original cost within just a few hours. At the beginning, some netizens ordered a small amount of the mispriced product. Many netizens later began to post photos about their orders and therefore led other netizens in PTT to behave irrationally and extremely. A PTT account with the username "connyli", for instance, posted the photo showing his orders were valued more than NT$360 million. By 7:00 a.m. the next morning, when Dell urgently closed its online order system, more than 43,000 orders, valued at NT$2 billion, had been placed from PTT causing Dell computer to almost collapse. The court, however, finally ruled against the PTT members of trying to take advantage of erroneous information to force Dell computer to sell below their cost. Thus the case was dismissed. But the mob rallying effects of the PTT went on full display in this incident.

Like all other anonymous or semi-anonymous internet communities in Taiwan, there's plenty of fake news and many acts of cyberbullying on PTT. In recent years, the most notable is one of Su Chii-Cherng (蘇啟誠), Taiwan's representative in Osaka, who committed suicide in 2018. Su Chii-Cherng left a letter saying he was suffering from hate speech received. His office was accused of not assisting Taiwanese tourists stranded at the Kansai International Airport in the wake of Typhoon Jebi. During the Typhoon Jebi crisis, fake news said that the Taiwanese tourist had to identify themselves as Chinese in order to be allowed to board China's bus that was used during the rescue efforts, and therefore led the other netizens in PTT to begin to criticize Frank Hsieh (謝長廷), Taiwan's representative in Japan. However, soon, a PTT account with the username "idcc" posted messages that claimed the Osaka office was out of Frank Hsieh's control and criticized the Osaka office should take all responsibility for the crisis. This was an untrue because the Osaka office directly reports to Frank Hsieh's office which was in fact the highest ranking government office of Taiwan in Japan, It was the Taiwan Representative Office. Yet, the Osaka office took the blame from the media and netizens. Su finally found it unbearable and decided to commit suicide. Prosecutors later found that the account's IP address could be linked directly to Slow Yang (楊蕙如), who is considered as pro-DPP figure and a member of Frank Hsieh's faction. Furthermore, Slow Yang was accused of paying and asking others to post such fake news in order to protect Frank Hsieh at the expense of Mr. Su's life.

According to the interviews from Common Wealth Magazine, one of the biggest business magazines in Taiwan, people try to form public opinions in PTT and seek to influence the larger society especially during an election year.

In April 2019, a PTT account with the username “ken4645” posted an article titled “Is Wang Jin-Pyng (王金平) and Han Kuo-Yu (韓國瑜) related to China's online warriors?” This article, along with several fake photos, alleged and accused that Farmers’ and Fishermen's Association South Information Center (FFASIC) and KMT presidential candidate Han Kuo-Yu received funds from China and tried to purchase Facebook pages for spreading misleading information in order to affect public opinion related to the election. However, the article was later proved to be false. The user spreading the said fake news proved to be linked to the pro-DPP group and thereafter was investigated by the prosecutor.

In June 2019, the Taiwan People News published a column written by Cao Chang-Qing (曹長青) which alleged that President Tsai Ing-Wen (蔡英文) paid off officials at the London School of Economics (LSE) to obtain her Ph.D. This article raised thousands of comments in PTT where many netizens gave their opinions based on this news. However, after several months, LSE officially stated Tsai was correctly awarded a Ph.D. degree in 1984 and proved it is false. But the authenticity of LSE notification is in question.
