Yeah, same thing has just happened with me. It's a yahoo.ca account that I've had for several years, and I'd get only a handful of spam a year. I was just reflecting to myself the other day how the address seems spam-proof. Then suddenly in the last week - blammo! Every day there's junk. One day last week I had 13 spam messages.I've had the same email for 8 years and got like 3 or 4 pieces of spam a week, but all of a sudden I'm getting 30 a day. This really sucks. I'm going to have to get a new email.
It's not like I used the address to sign up for....something that would cause that kind of result, heh.
