Where do I find some reliable and updatable lists of "bad" and legitimate crawlers?

I have a very large reference site and bad crawlers are huge problem. I have some automatic IP blockers, but a reliable list would definitely help in this war.

Also, having a list of "good" crawlers could allow for easing of filtering rules for legitimate search engines.

I know that Yahoo and Google share a block list, but I don't know if it is public and where to find it

One size doesn't really fit all when it comes to what agents you wish to allow, however this thread may give you an idea A Next to Perfect Ban List - Part 3 [webmasterworld.com].

Be careful of just cut'n pasting without knowing who/what you're blocking.
