Alright here is what annoys me most.

One think that is really niggling me about the moderators right now.
They are locking all threads that are opinions because they might "lead to a flame war". There really isn't any reason to lock the thread if it isn't flaming anyone. If the thread goes off topic and the poster of it had nothing to do with it than instead of locking the entire thread just delete all the off topic replies and give the users that went off topic a warning.

Another thing that annoys me.
Different moderators will give different punishments for the same rule.
Let's say that Moderator bob gives a user a warning for posting in the wrong section (which is the appropriate punishment for that) but moderator jack catches another person posting in the wrong forum, jack gives him a 1 day ban and moves the thread.
That has happened before and it is really unfair.

Another few things that bother me.
When a moderator will lock a joke thread because they don't understand the joke or they don't think it's funny.

When a moderator will lock a thread for no discussion value because they can't think of a good reply or it has no replies.

When a moderator tells you to PM them because of a thread you post about it than ignore your message.

When moderators create their own rules and doesn't tell anyone about it.

How vague the current rules are.

Now I could go on with this longer but I will stop here.
