I think those spammers have found a bug to get spam through Gmail’s filters — attach a 1kb zip file and boom, they get through. And I can’t stand it. I think I might have to go back to SpamArrest soon.
The reason I think it’s pointless to start a new email address is that I think people’s email accounts get hacked into, then spammers scrape the emails to find out who those people sent to, then rebuild their lists continuously. It’s a losing battle.
