Great it helped. Haven’t investigeted in the reason what’s different either, but maybe we don’T need that right now.
Regarding new bots, I guess we have to keep our blacklists up-to-date manually. Sometimes I even have to remove an agent from the list because some customers have issues with them from time to time, when one of their applications comes with a user-agent that matches a line in my blacklist. Probably there is a recommended list maintained somewhere on the net? Maybe worth a search.
