Why are the administrators allowing this spam the continue?
Non-newbie users should not be allowed to start new topics in this section of the forum.
I will not sign-up with TradeHill because the incentive that they offer promote spam.
I am not down with the spam either (see my signature, click it only if you find it amusing, not because i'm whoring the link out, I want the referrals for the right reason).
Anyways, a person representing TradeHill is not down with the spam, it isn't necessarily their fault the situations are causing everyone to give them a lot of attention. See his post (and more regarding this situation) here http://forum.bitcoin.org/index.php?topic=19709.0
