It appears I have also been booted from Top Guest. Checked-in using 4SQ, usually at the same hotel, but I also had big gaps between check-ins. Tried to log into my account the other day to see why points hadn't posted this week and when it didn't work I came here. It would be nice if their IT department could at least have some kind of message pop up saying your account has been closed, rather than just having you enter your password, hit enter, then have it flash back to the log-in screen. Oh well, it was fun while it lasted.
