As far as I am aware, there is nothing that is doing Sybil detection at the Bridge level, and I don't really think that's an arms race that's winnable (even at the standard relay level, it feels like an uphill battle). If I were to hypothesize, it's probably someone's botnet/malware or something (in both cases), but that's just a guess and it could be something either more nefarious, or more benign.
