Well, I would hope that they would be lenient in cases where this was an honest mistake, but I do agree that trying to game the system is poor ethics.
DreamHost does allow you to have more than one hosting account, but have two things (that we know of) to discourage rolling promo code acccouts:
1. The restriction, that others have mentioned here, against moving domains previously hosted here to a promo-coded or referred account.
2. The verbiage in the Terms of Service prohibiting you from having more than one account.
Item #2 is what would, if enforced, lead to the termination of your account for your violation of the Terms of Service.
I agree, though I wonder about the "dim view" part. DreamHost is upfront, radical, and at times, straight-shooting confrontational with their rivals. I dunno if they'd out-and-out restrict such a signature.
I do agree that it's biting the hand that feeds you to have such a signature. DreamHost provides this forum for its customers (and anyone else, for that matter, since registration is open to anyone, not just people with an account here). Should one then use it to direct people to a rival? I don't think so.
I do admit to making specific recommendations to people who have specific needs for either hosting or nameservice management that aren't satisfied by DreamHost at the current time, but I think of that as being like Santa in Miracle on 42nd Street.
