The mods on this board have a hard time, the users do too. There are lots of people just spreading (fake) spoilers in the threads they aren't supposed to be in, talking smack to other users etc etc etc.
It's impossible for the mods to see and check EVERYTHING, so why not a report button which can be used by the users to point out ''illegal'' posts from other users? Should help clean this board from bad users and such.
Edit: and yes, I know you can always PM a mod. I just think this would be much handier.
