Went through your entire squad of 25 members. There has been one instance of one of them losing their text privs, and that was last year.
I went back to October of last year in the moderator logs (yes, the moderators are monitored) and could not find a current game ID in the list of any of your squad mates.
So, who are we talking about here? They could have changed their game ID between yesterday and today. Of course, we do have those logs as well.
I do not appreciate the implication we at HTC would remove anyone's privs for a "disagreement". Please provide the game ID of the person you are defending, at your earliest convenience.
