In the hands of spammers, TinyURL has the potential to sag under enormous demand and attract the vociferous complaints that spam can incite. Gilbertson says he disables spam-related URLs one by one, following tips sent to an abuse address and notifications by SpamCop, an antispam group.
What I like about that plan is that it renders spam URLs useless. If he can disable a URL included in 100 million spams right away, then that’s a fee for 100 million spams that was completely wasted. An unhappy customer of a spam service is a very good thing.
