In this posting included on the Issociate.de site's Newsreader, there's talk of a "massive phpBB hack" that might be taking place.

During the last few days a bot using a name FuntKlakow, has been registering to at least hundreds (maybe thousands) of phpBB forums.

Ok, what is a danger? Next time the phpBB announces a critical vulnerability, the bot would have everything ready (just a post click away) from attacking thousands of sites/forums.

It's an interesting situation and, as suggested in some of the comments on this digg post, will be interesting to see what happens. It is a little odd for that many items to come up on a search for the name that are only profiles for phpBB boards, especially given phpBB's track record...
