The anonymous user, you mean? Or did someone just find photos of him from social media accounts and Say that account sent it to them?
It's all speculation. There has been nothing to confirm any of that.
Right, and I have said all along that I believe there is someone out there who has been attempting to make these two(specifically Bryer) seem worse than they are. The day an account was last active says nothing. I expect there are many accounts out there who have the same 'last active' date. That same date would show if you were to set your profile to 'offline' as well. So someone could have simply set their accounts to offline, and changed their profile information.
I believe there are two of the same friends from SM.
Everything doesn't point to that though. It is just speculation.
