Hey Jered,
I am very pleased to see you guys dis-associating yourself with the slimy spammer that is blasting his referral code out there to everyones emails. Might I suggest that you create a thread on the forums requesting any and all codes that were contained in these spam emails? I know you mentioned you were taking actions against the user in question (by negating his referalls) in another thread, but it would be nice to be able to post these in one place.
Here is the latest code I received about 10 minutes ago: TH-R15683
Tradehill should do this, for the bitcoin and their own good.
