Ah, that's just an odd glitch where someone loses connection, and for some reason another person (sometimes you) find yourself controlling someone else's character, and the chat is seen as "<? ? ?>". Nobody else can see it, of course, and it doesn't mean anybody's been hacked (if that's your concern).
It's just an odd glitch. Exit the FH window, then log back in, and everything should be foin. c:
