Companies usually cover themselves for anything in the T-C's, but AFAIK, the court doesn't always uphold their T-C's, if they decide it's not according to the law or they just see through it.
With 90k UR, I think it's worth a shot. The one thing I'm worried about is infuriating the Chase crackdown dep. even more, those resulting in a permanent lifetime ban.
