What if a user friends me that is glitched?

'''DO NOT ACCEPT THEIR FRIEND REQUEST. '''They most likely are either hacked OR are the hacker. If they friend you, get as far away from them as possible, ignore the friend request, and make sure you have your password and secret question be as long as possible and have random digits and letters in them.

If they follow you, LEAVE KART KINGDOM AS FAST AS POSSIBLE.

NOTE: If they are invisible, its fine. That's a harmless glitch.
