Until the US legislates to kill spam, and judges stop giving the spammers rights, it will not stop. It's madness, spam companies are suing companies who block spam emails. It's insane.
I've never had a single one on my ATS account, though!

Outdoing most analysts' worst predictions, spam accounted for 82 percent of all U.S. email last month.
After a two-month drop in spam, the number of unsolicited bulk email skyrocketed in April, bringing the saturation number up to record levels here in the U.S. and across the world, according to MessageLabs, Inc., a security company based in New York.
''This is as bad as we've seen it,'' says Paul Wood, chief information security analyst for MessageLabs. ''I think it's likely that it will continue to rise but perhaps not at the same rate that it did in the past month.''
And April did show a dramatic increase.
