I think you have some kind of a virus. I'm getting penis enlargement ads from your Yahoo address. Unless of course you're actually concerned with the size of my penis and... well that's just creepy.
I'd been getting crap from a few other people on here, only one I can think of right off the top of my head was Fred Vegas, apparently it's something that gets into your hotmail or yahoo account and forwards things to your contacts. Deleting them from your contacts and using Gmail seems to work just fine.
What email address? A friend of mine was getting email spam from an old address of mine, deaddrunk7@yahoo.com I think, and it's an email I can't even access anymore....sorry about that. Good luck with the penis though! EDIT: I now see you mention it was from a yahoo address, I haven't used any of those in years.
