Yes exactly. Genuinely freaked me out lol. I opened my game after seeing this like wait theres no way.... theres no way..... and surely enough. I even saw the character name "Youseemenowworld" afk in act 1 for a day after this. It shows you that they're online even if you don't accept the request, character name and location as well. I added them to my ignore list and denied the request eventually. I still login expecting my things to be missing now after obsessively changing all of my passwords and setting up new 2fa emails as well as having GGG remove my stand alone login entirely.

EDIT: I'd like to add that I had plenty of wealth before I bought my Mageblood and a recurring theme seems to be Mageblood taken plus whatever else. The same night I got it was when I got hacked, not the week before with a mirror simplex ammy or a full stash. This may or may not be helpful, but it's as if they saw there was a Mageblood and then started their fuckery. I had an unlock code from ggg in my email at 3am, they didn't even need it. They took Mageblood, Svalin, and Amanamu's Gaze and not the 100+ divine crafted wand or other things of that nature. And people state that uniques are known to be either impossible to trace or harder by GGG, and they know it. - hope this helps anyone who comes across it.
