Вот, что пишет о своем сервисе 10minutemail.com:

When I launched 10minutemail.com, tons of forum admins decried the idea. They screamed that it would let spammers on to their forums, and that they wouldn't sell e-mail lists to spammers, etc...

A month goes by, and let's see what we have. My server used to get around 200-300 e-mail a day. In the past week it averaged 60,000-70,000 e-mail a day. Virtually all of those were to old (expired) 10minutemail.com accounts. Presumably virtually all spam.

70,000 a day!? This proves that the average person simply CAN'T trust a random site or forum with their real e-mail address. Are there some forums/sites that are trustworthy? Sure! Does the average net user have any ability to tell with certainty if a given site or forum will sell their e-mail address or spam them direction? Unfortunately not.

This drives home the importance of the service.

In order to save my server from the crushing spam, I've swapped out the e-mail domain to fificorp.com, and then fificorp.net, and will continue to swap out the e-mail domain on a regular basis. This will serve two purposes. One, it will save my server from dying under the flood of spam. Two, it will keep admins who block registrations by domain on their toes at least once a month.
