Two things:
1.) This is analogous to calling someone a cheater (at the very least, it is the spirit of that rule).
2.) Moderators ARE moderated. Help->Rulebook->Rights->last point:
Mod & admin actions are logged, and can be checked over if requested.
We have said multiple times before that you can ALWAYS go to admins and kestas regarding any particular ruling or moderator or admin to be reviewed. We do get requests.
To do this, though, you need to email the moderator mailbox, request that an admin review it (if it is a mod, or email kestas if it is an admin).
Attempting to get a lynch mob started, though, is counter productive. So, please, if you agree with me, no need to reply. If you agree with Lando, give specifics and email the moderator email and request an admin (you can even use me, specifically) to review it.
