All of the hits are from Anonymous Monk, and all are submitting queries to Super Search — which, of course, is quite resource intensive.

Maybe there should be a rate limit for Super Search and other expensive functions? Applied only to Anonymous Monk, so that regular monks can use Super Search as usual. A sane limit might perhaps be something like two or three searches per second per IP address, and no more than perhaps 20 per Minute per IP address. That would still allow a few Anonymous Monks behind a masquerading gateway, but would block robots.

Or, a little bit evil: Require a login for using Super Search. Yes, it's at least annoying for people not wanting to create yet another account. On the other hand, a Google search with site:perlmonks.org works quite well, so Anonymous Monks could use that.
