I don't condone the radar cheating, but I also don't see what they can do. It reminds me of when some states in the US tried banning radar detectors in cars. Most courts found that the signals are there to be received and it is not illegal to receive the radar signals transmitted from police/authorities. Of course, this is a game. And SE is the judge/jury/executioner. However, I don't see how they can do anything. The radar cheat probably just reads in whatever the server says is in your view. I can see them doing something if people were teleporting around.

It is depressing. Probably one of the reasons I don't touch frontlines and won't do hunts unless I'm in a big LS doing it. I can't compete. It is a problem.
