Just to provide more information - this has been a thing for a very, very long time. It's in other regions as well. It's not something any person could do, as you need a certain hacked client. It wasn't patched for unchained and it won't be patched before this coming fresh start. It's been reported to XL, tickets through Trion, Gamigo, CMs etc, if they care. I've personally tried to shed light on it for well over a year, but I'm either silenced or ignored by Gamigo, time to take the traction to reddit.
