I have been furious about the spam... I check my mail 20+ times a day, and easily have 50 new spam messages in there each time. I checked a couple that seemed somewhat harmless for their sources and most spam in other accounts in the past have actually stated the full "name"@account . com/net however I noticed on a few in Gmail, its just "similar name"@ gmail.com. It's almost as if Gmail sends the email to the account that "most resembles the to: address.
