What I like in Facepunch is that if you're helpful, you will gain Useful and Informative ratings. So, like rep gems, a certain amount of ratings will give the user the badge/shield.
Concerning trolls, maybe a Dumb rating should be introduced. On the one hand, it does deter people from behaving stupidly but on the other hand, it can be harsher than neg rep. I really think TSR should have quality control. The more I think about it, the more Facepunch seems appealing. The LMAO pics thread is actually funny. No two threads are the same. No AMAs. People get banned if they constantly put up troll feminist threads in a matter of hours.
