postnazi 

A person who deletes posts from message boards because they do not agree with the opinions expressed in them.

I can't beleive she deleted all my posts, what a postnazi. I bet she hates people who don't share her ethnic origin.

postnami 

Combination of the words post and tsunami.

When something on a message board breaks and suddenly all the lurkers come out of the woodwork to complain.

"Holy shit, what are all these weird people doing on the forum posting all over the place?"

"It's a postnami. We're waiting for the admin to come on and fix the site so they'll go away."

Post Nazi 

Someone who finds a particular thread offensive and rather than politely PM the member who posted it, with a polite message to please remove or edit the offensive manner ....contacts a Moderator and starts crying like a baby.

Why did my post get deleted?

I bet some Post Nazi hit the mod alert button!
