Just a little tiny and probably amazingly easy feature request... this would cut down on the number of crap results of a search:

On start up generate a random 32 byte string (like MD5 encode the thread ID and systime or something). Do a search for it in the background. Automatically blacklist the IPs of anything that returns a result to that search. While running, preodically do this search again, and add any results to that blacklist. Optionally, also give the user the ability to add obviously BS results to this blacklist, and possibly even allow this blacklist to be auto-shared, so you can choose another user and import their blacklist if you want.

I'm hoping these features are significantly easier than what I really want, which are features that get you a beer whether there's any left or not, and make the cat not decide to take a really stinky crap every time you have a girl over. B^)
