It's exactly like the real thing, except it's all fake.
The goal is to post as much as possible in 30 minutes without getting banned. There are 35 threads to start, and a new one appears every 1:30 to 3:30. New posts will appear every 1 to 15 seconds. Around five threads might be locked by the end of the game. Prior to the lock, the fake robot posters will flame each other, go off topic, spam, etc. with no two of the same fight/spam/etc. per game. Gotta stay believable! All posts are predetermined and relevant to certain topics... may want about 250 generic topics and 4,000 generic posts, which probably seems like more than it is. People could submit ideas. No two fake users can have the same post in a game. If you start a topic, the game will scan for important words that match things in the fake posts. Posts with similar important words would appear in your topic. It could use a similar system for people who quote you to see if a user agrees/disagrees.
I am so very tired of using my brain today.
The game checks your spelling, grammar, posting habits, words, etc. to see if you need to be banned. A warning point system could be used (but you wouldn't see your warnings...). Major rules could be worth up to five points, while minor ones could be worth one. You might be banned at 15-25 points... depending on difficulty, maybe? Yeah well, you get it, bad posts mean a mod bans you.
Well, the point is, it would look like people are actually discussing something. Maybe posts could have tags, and posts with similar tags could be in a thread together... you might be quoted if a post's tags match your words (Might have to prevent "I don't like beans..." "I like beans too!" somehow). After 30 minutes or being banned, you can submit your post count to the high score tables. UGH I'M TIRED OF THINKING. Certain topics could play out the same way every time to make it look more authentic. 50 pre-planned topics with around 10 posts each? It would have to be a huge collab or something. You can probably imagine the rest... I'm done.
