What's someone going to do? Look up Thailand in the phonebook, call the first # they see, and say (in a language they wouldn't understand)...
... "Hello, I want to report a questionable website based in your country. It's being perused by a fat sicko in Torono who goes by pumphard. Can you please shut it down so I can sleep better at night 4,000 miles away. Oh you'll do that no problem? Gee whiz, thanks guys"
STFU unless spoken to fatman... smarter men than you are talking here
