As much as those who don't like edgy characters...

This is a trend I noticed more in lower level RPs: overly crazy characters whose insanity don't fit well within the RP context. Nothing wrong to create a nutty type, but don't go overboard and turn that madness into indirect cyberbullying. Other players are nice enough to close one eye to the uncalled intrusion, so at least be polite enough not to act like a douchebag on their characters with your terrible attempt at making a Joker clone.
