roblox battlegrounds scam 😞😞😞

so there is a game called jump showdown or jsd and I was playing it with my friends but then randomly some guy came up and said to me that duel me if I win you give me an galatic brainrot and I said sure cuz I have 4 to 5 galatic brainrots and he won against me so I kept my promise and send him my server link to come but little did I know that he also told his friends to come and when we were talking all his friends came and took my galatic brainrots away so I advise not to accept a duel like my self next time.
