Would you lose traffic by rejecting their bots? As far as I know traffic comes in on its own IP/UA - but I could be wrong. :)
Whatever, I have those IPs blocked and last year one site received a couple of thousand hits from five or six wikis (different countries) (last year was latest stats processed for this site).
