Casey Ho @caseyho.com · 30/01/2025Given that the accounts in this spam network are friendly and rarely blocked, one might wonder why they are a potential problem. The answer: the accounts occasionally switch to posting affiliate marketing links for various products including a "AI detector" browser extension of dubious efficacy. 1252
Casey Ho @caseyho.com · 30/01/2025The accounts in this spam network have been active ever since they were created two months ago. Over 98% of the posts consists of quotes of random Bluesky users. The text is often friendly and affirmative in nature. Interactions that lead to blocks are relatively rare. 1234
Casey Ho @caseyho.com · 30/01/2025Here's a riddle: What does this hodgepodge of accounts- covering a range of topics from sci-fi books to tech news and politics- have in common? Spoiler alert: They are all LLM / AI reply bots that spam hundreds of users each day with quote posts. 36117

Casey Ho @caseyho.com · 07/12/2024As it turns out, all but one or two of the 9858+ reposts are spam. Every single reposting account has zero posts of its own and has a random fill-in-the-blanks description. A chart of the creation times shows clear unnatural spikes, which indicates the use of multiple methods of account creation. 47922
