All good spots.
Last three are bots (the one quoting the post with no content is clearly broken/experimental phase).
Tips for suppressing shillery:
1) Find common ground in posts (shills rely on scripts and automated posting, and will classically repeat themselves/reuse the same tactics)
2) Apply systems that impede that style of shilling (depends how much 8chan/Qboard want freedom of speech over quality. The more moderation, the greater the quality but the lower the freedom of speech. Expect shills to bitch.)
Easy win tips:
1) Minimum post length (I'd place it to be with a minimum length of roughly 80 characters).
2) Name filtration (bot always uses the same name, why? It also looks like the name is designed to be unique - do you think it's so it can find it's own post to confirm successful posting? Incap bot's name = incap bot's posting)
3) Optional: Requirement to supply a link in research threads (???) when posting. Then block all the trash URL links.
4) Optional: Build a hunter-killer robot whose job is to track every thread post, and when given examples and IDs, can pull back every post that has that ID/format (this would allow bulk moderation on a single target, allowing you to wipe out a shill's handiwork across multiple threads at the same time)
4 is already possible. You've got tools to filter out Q's posts. Reapply that thinking to shill IDs, clownfag names, or just post content in general. (EG how many posts are just garbage accusation posts?) Massive protip for highly responsive content: use SQLite and pre-cache the posts in a database where lookup is easy (might not be real-time, but stops you from being forced to webscrape the entire board, refresh only periodically).
