If they were smart and had their own relays it would also make them more likely to be selected proportional to how many other relays they took out. Looking at the number of relays and "bandwidth advertised" graphs on metrics.torproject.org it doesn't look like they've made much of a difference but it's interesting nonetheless.

To me, the worst part is that "Watchdog Cyber Defense," Spamhaus, Shadowserver, or some wannabe extortion artist like UCEPROTECT can submit millions of automated reports that hosts are de facto required to listen to lest their IP space be blacklisted.
