Should both groups be dropped at the BridgeAuth or what?  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.
