Why Didnt you get a warning

[-J-]

To expand on what Barbie said, the one major check on the in-game mods' power (and that of forum mods) is the support email which Vadim regularly checks and responds to. It is not uncommon for in-game bans to be overturned after review for a number of reasons, including judgment calls made for valid reasons (a number seem to be jokes gone horribly wrong; don't kid about being under 18 when you're clearly not!).

Another check on that power? Other mods! If one gets too trigger-happy -- or doesn't pull the trigger on a ban that seemed obvious to another -- I can guarantee you they hear about it. Because another mod will get the question "Why was so-and-so banned, they/a friend wanted to know what happened," and then there's a discussion -- some brief, a few longer. If it's because of an error that can be corrected, changes happen.

None of the moderators on MnF do their job in a vacuum.
