While active on Twitter, Dappi made a number of false or defamatory claims aimed at swaying public opinion against progressive opposition parties, which led to the targeted individuals filing a lawsuit.
[1] Almost all tweets were posted during regular office hours, roughly between 9 a.m. and 9 p.m. JST, and rarely on weekends, leading to speculation that the account was not an individual activity[3] and that there was a coordinated or organized effort behind it.
[1] In July 2020, the Cabinet Intelligence and Research Office responded to a freedom of information request seeking government records related to Dappi by refusing to confirm or deny the existence of such records, citing concerns that doing so could potentially "impede the effective execution" of their duties and "pose a significant risk to national security".
According to Newsweek, the wording of the response, which indirectly implied a connection between the account and the agency, further deepened suspicions surrounding Dappi.
[14] Dappi had been criticized for posting highly biased[3] video clips that were edited out of context,[5] creating a false impression or misrepresentation of opposition parties and media outlets:[11] In 2021, Hiroyuki Konishi [ja] and Hideya Sugio, members of the CDP in the House of Councillors, filed lawsuits against Twitter and an Internet service provider at the Tokyo District Court, seeking the identity of the entity or individual responsible for Dappi's October 2020 tweet falsely accusing Konishi and Sugio of driving a Ministry of Finance employee to suicide.
