updating members?

I was just wondering, how often do you (admin) clean up the member list?
like, as in deleting the banned members, those who haven't posted in a month or so, etc. you know ^^

We delete the weakest members, who hasn't post any threads when 3 or 2 members "register"

i was just wondering...
what if you made a code that basically does this:

1) check last post date of member
2) check # of posts
3) If [# of posts == 0 and registered date == 3 months ago] or [# of posts < 10 or so, and last post date > 3 months ago or so], then
4) delete member

whaddya think?

We just delete all zero posters. We can't get the member count under 1,000 though, so there's not much of a point.

oh, well in that case topic solved?

No problem. Glad to help you.

As the problem is solved, I'll lock this topic.
