Well, as you may have noticed, you're not a lurker anymore.
Why? because you participe. You post stuff. Either it's "thanks", or "where is the porn"...or everything you posted above.

Nobody is kicked out unless for a good reason: breaking the rules is the major offense.
And the second one is being a lurker. Being somebody that comes here to take advantage of the hard work of some people and comes back later for new passes.
That's lurking.

To avoid a mass flooding of lurkers, our beloved admin cleans the place sometimes. He looks (hunts ?) for members with 0 posts in the database and wipes them off.

As for the history of a member, well, if this members behaves correctly, i don't see why he would be banned. Mods are not that mean!
