Thousands in bandwidth charges and site unreachability.

TYPE OF ATTACK:
White supremacist radio show host published phone numbers of crank callers. "Anonymous" (loosely associated users of 4chan, 7chan, and other sites) launched this attack. Turner later filed suit to recover monetary damages, but it expired due to Turner not responding to court paperwork.
