Nobody actually knows. People have been banned for violations of the stated rules on each board despite not actually violating them, people have been left alone for flagrant violations of said rules. Board features like names, macros, and so on are toggled on and off more or less on a whim.
To say that 4chan's enforcement is inconsistent would be an understatement. But, the chaos is a feature, not a bug. Something to keep in mind.
But for everyone else, this is one of the reasons I think seriously that 8chan is the next big thing, it's basically Reddit, but for image boards. Mod abuse (real or perceived) will result in community fragmentation but on the same site, rather than exodus to other sites.
