Someone is spying on me in Kart Kingdom (Following me around), what do I do?

If a user is following you, it could be many things. Now, the last one is EXTREMELY UNLIKELY. There are around 3 reports of this happening. You are most likely safe, and you can play with them.
 * 1) Maybe they want to be friends.
 * 2) They may be very nice.
 * 3) They want to say hello.
 * 4) They are a fan of you.
 * 5) They want to ask a question.
 * 6) They know you from the blog
 * 7) Maybe they want to hang out with you.
 * 8) (EXTREMELY UNLIKELY) They actually are trying to hack you.

If they are glitched, (Being invisible doesn't count, that's a harmless glitch.) then get away from them.
