Obsession with twngan

Gmail is no doubt the greatest thing happened for emails, and I converted the first day using it. But it has this annoying "feature" which matches mails sending to nonexisting accounts to the account with the closest name. This feature could potentially be useful, along the line of correcting people's spelling errors in search engines. Yet this is a very dumb idea for emails, since there are so many spammers simply spamming generated addresses, and Gmail would try to make sure that all those spams would get to some people's inbox. I've been receiving much more spams lately just because of that...
