The global font needs to be an option by default. I had just installed it before logging in, but if I hadn't I wouldn't have been able to identify them which would have made it harder to catch them.
But more importantly, we need this issue resolved. We have no way to fight back but this isn't PvE atm. It's cheaters wrecking the rest of us and we are helpless unless we start cheating as well (I'm not advocating that we cheat, just stating that the current state of the game gives
no other in-game option to combat them).
Sorry to hear you got attacked as well. This is far too common.
