For those of you that run a forum, here are some things you should know about what mods should/shouldn't do.
1. ---Private Message---
What's your password?
A good moderator would never ask for a password

2. "Hm... I'm bored... I'll ban these guys"
Members shouldn't be banned unless totally necessary

3."h3110. 1 @m 73h r0xx0rz!"
Moderators should use proper English (It doesn't have to be perfect spelling or anything, just proper grammar)

4."Ha ha! You're a n00b, you don't know how!"
Moderators should help unexperienced and/or new members, not make fun of them.

5. "***** **** ***** **** *****"
Moderators should not constantly swear.

6. "Do it or your Internet will be shut off"
Good moderators do not threaten users, unless it's something silly like "View my thread or I'll destroy you!" or if it's 100% necessary and the user has been extremely abusive.

7. "Ooh! Look at these controls! "Beep! Boop! BOOM! YAY!"
Good moderators don't get pleasure out of destroying the forum they run. They use their moderating powers for good, not evil.

8."I just made a new hacking software. I'll put it in the graphics section!"
There are two things wrong with this. Good moderators put things in the right section, and do not post warez.

9. "A helpful thread! Locked! Spam! Stickied!
This is all backwards. Helpful threads should be stickied and not locked, so people can see them and post comments. Spam should be locked (AND deleted) so the problem won't come out of hand and so only one person will receive an infraction.

If you have any more ideas on what good/bad mods should do, post them here.
