Porn games, Sex chat

Hello,

I'm not quite sure where to report this issue I'm having but it started to be a bother for me, someone is impersonating me in Achat as if they are me, that some friends and random people in the other games I mainly play or hang in mostly, not only they did impersonate me by the name alone, they even copied the same profile info I had in my other game as the age the location, etc, which is even more creepy and weird, not only that they even dared to actually steal my own profile photo that I had as commission from a friend and uploaded it in Achat for them.

I honestly thought to ignore it at the beginning and it started to be an annoyance for me, as more people and more friends assumes that is me or ask me if that was me and I have to say no and sound all awkward about it. So what can I do to file a report against that specific person and their impersonation to me? Because it clearly started to be a sore problem for me more than just some random person liking my popular name and decided to just use it to get attention.

Any help or advises are really appreciated and welcomed.

Thank you.
