a new kind of SPAM

For the last several days, I keep getting emails from addresses that contain part or all of my own username in them, with a different domain! Now THAT is bizzare! Looks like a new kind of SPAM to me. I am so sick of it all - I don't need a penis enlargement, performance enhancer, asian girls with shaved pussies, or russian child-brides. UGH when will it all end??
