Stay Away From This Player

I was playing on roblox on a game called "Natural Disaster Survival" And there was this player called BobJrPerson. All that guy did was stand in one spot and did nothing else. I approached him and touched him thn he started to play the game. When I tryed to add him he said. "Stop it Curtus!" Exactly like that. (Curtus is my name." And then I quited the game and went to a new one he was there. When I saw him I started to freak out so when iI went to a diffrent area in the game. It was "Robloxian Life." And there he was faceing me. I quitted and did not play for the rest of the day. I went into his profile and he was online each time when I went on he was online. When he is not fallowing someone he acts like a normal player. I say stay away from him.
