Oh, right, I actually forgot that .tv was actually a country code and not a TLD for television.

So... my apologies to the 12,000 residents of Tuvalu. I'm sorry to have to block you all, but for some reason your country code attracts spammers like flies to honey.

Correct me if I'm wrong, but I think .tv domains are pretty pricey. They're loved by people who need a bulletproof domain for their sketchy business but I don't see how they would be useful as a disposable spam source that's going to get burned quickly anyways.
