Community is changing, so should the rules.
OH MI GAWD HIIIII MOD. *warning/kick*
It's spam, useless and it takes up the chat, it gets in the way of real questions. Should be handled as spam, definitely when there are eight people yelling this through the chat.
HIII MOD SAY HI BACK! I LOVE YOU MOD!
Really I don't think we really care if the MOD says hello back. Shut up, and let them do their job and leave. Mkay? Spam as well. Should be treated as such.
It's almost harmless when one person does it. But when there are eight or more doing the same thing, asking the same redudent questions. OMGGAWD MOD DO CHU LIKE GUMMYBEARS?!?!?! It becomes an eyesore, you can no longer see ads, if you actually had a real question it would be flooded out.
Really not worth ban hammering someone over. But it would help teach people.
Just an idea though. Feel free to lock once your done.
