Finding a scammer in ROBLOX....

I got a person in sniper arena where he was trying to trade with me.he said he will give me dynamic MA 200 legendary at the price of rare ssg acid fade I declined other day the same person came in superhero tycoon and said he had my second account hacked in my pc I m lucky in that time I was sitting near my pc and checked I found that my account is not hacked. he said I have to give him 100RBX I noted his account pls if anyone could see him leave or change the server .. Tip :- If anyone says your account is hacked or says that he/she is your friend saying with different account, pls check or you will be scammed....... Account of scammer:- fLu@a112
