Opt-In is a term used when someone is given the option of receiving bulk e-mail when they are registering to some sort of database system. This technique implies a number of practices that will ensure correct ways of managing e-mail marketing campaigns.

Spam bounties, or rewards leading to the arrest of spammers, have been considered by the US government. In 2004, Congress requested a report by The Federal Trade Commission which concluded that rewards between $100,000 and $250,000 would be necessary to make the program work.
