Can AL be hacked?!

[arcanefid]

So apparently my friend's account got hacked by someone who knew her and me. I had my gears and pets on that account. So my friend told me that her account got hacked and she can login anymore. At first yeah I thought maybe she scammed me, but had a lot of talks and turns out I can't make a decision. Today that " hacker " guy pms my friend on fb and says he wants revenge from me because I trash talked him, he said he won't return anything now.
Tbh I never would think AL can be hacked like that. I contacted support but I don't think I'll get my stuff back. Don't know what to do now ffs......
P.S: not a phising site problem

Trash talking, "had my gears on that account", now you're not sure if you got scammed or hacked?

I thought you were pretty good at detecting viruses and hacks and stuff?
