I threw together a very basic PHP script you can use to check your trust level. All you need to know is your Battlenet ID (e.g. Rico#2593 in my case) or your forum profile URL (Profile - Rico-2593 - Overwatch Forums for me)
It also requires you to have not been false flagged during the initial storm of the new forum launch, sadly. So, if you happened to post on any controversial issue at all, gg forever trust 2.
It’s not. If you have been actioned on the forum you can’t reach trust 3. A lot of folks got the minor suspensions from the false flagging that was raging through the forums at the time around launch. They will be forever trust 2.
