The forum is wall-to-wall shitpositng but I don't think this is the solution. Simply banning the crapcoin campaigns that do nothing but pay for any old broken English spam would go a long way and is the bare minimum we should be doing but if we were to charge for anything it should be for a signature.

Hah, my suggestion to charge for sigs has taken hold subliminally!

Not quite. I've been suggesting we remove signatures from ranks for years.
Dedicated spammers/scammers will figure out a way to game any system
I don't think they'll be able to game paying a hefty fee for a signature, but any way of being able to achieving anything here naturally will be gamed/abused though.
such offenders be automatically temp-banned if, say, x different members mark any of offender's posts as "shitposts."
This would be abused. People would just report or bot people's posts they don't like.
