There are two different aspects of "trust": there's the red and green numbers which are of dubious value as has been discussed many times here, with accounts being sold, farmed accounts, alts, personal politics and general abuse of the system.
Then there's old fashioned trust, where you are judged on your actions and words before someone else decides if you are worth anything.
Carrying a signature of a very dubious start up and playing ponzis would indicate to me that a user will do anything for money and I would assess them accordingly.
Your weak excuse that "everyone's doing it" doesn't cut any ice with me.
