I noticed this too. I've gotten about 4-5 abuse complaints to my upstream provider alone in the last few days. A few more directly to my email. According to the abuse report logs they all appear to be a similar xss exploit attempt.

Subject:[tor-relays] Noticeable Increase in Abuse Traffic

All,

I'm getting about 4x the abuse traffic that I normally get from running exits.  Anyone else noticing this trend?
