I feel like there isn't a good system setup for banning bot accounts. If someone (a bot) is spamming a website link or certain phrase then it should insta ban them.
Example, if they say "www.linkhere.com Sell/Buy meseta, use code blah..." I think you get my point. If they say that 3 or 5 times within a certain window like 15 seconds or 30 then it should ban them.
Example, certain phrases should be blacklisted to say. I'm sure someone can get a collection of sites that bots spam and in the system you can make it so they can't say those sites even with the spaces in them.
I hope this really gets looked at. Don't forget, report the bots
