Maybe it is time to report them to moderator?
By the way, these are not some random newbie accounts. They are all shill/bump bots posting copied messages over and over again in their own scam ann threads. I have between 70-90 of these banned last month but they just have/make more of them.
I stopped reporting them a while ago, there is literally no point other than increasing your good reports number. Just let them pay for copper membership, pay/lose additional $200 bucks to set up their scam.
I've noticed that as soon as they get painted in red, bots relocate to a newly created scam and do the same. StateStreete, Buildan, top100exchange, Offerzone , Bitdouble.Casino, Koala and many many more...they are all controlled by the same people.
Quick example, I'm picking a random bot - ubiheal200 and his last post:
The current bonus is very good enough, I suggest to invest now
The current bonus is very good, I suggest to invest now 
I'm all ears if someone has a better idea how to deal with this.
Reporting hundreds of newbie accounts for plagiarism non-stop is tougher than you might think.
