But yeah, they should buy up the domain names. $15? Get 'em for $8 or less if you buy in bulk.

It would probably cost them only about $1,000 to shut down the porn site, if they wanted to. Basically, the fees to file a dispute with ICANN. Maybe less, if they were willing to sell. Most people just register a different domain name if the bandwidth vampires steal theirs, but occasionally, someone fights back. One site asked for donations, and got enough to file the dispute and get their name back. Another had a benefactor who bought the domain name back for them for $200.
