design question

[Matt]

Well 5 spammy posts in 5 mins are always deleted and the user ends up banned.

Typically a legit user posts over the course of a few days or weeks. Questionable users post over the course of a few days, and bots usually do it all at once. I am sure now that I said that the bots will be updated to post every 4 days to get past the measures.

Now we need to find a forum mod to do this automagically.
