I got banned for selfbotting giveaways but I didn't do anything

Dear Admins, could you tell me what i did? i only reacted on the giveaway once?
My Discord is SchrottTV#7383

Hello, you reacted to a giveaway that said “do not enter, you will get banned” or something in that regard - we create these to catch self-botting users off-guard. Perhaps you have not read the message under and above the giveaway.

You can appeal for an unban if you directly message Revyn#0612 on Discord

Really? but it said something about a game and several people were reacting

Okay, added on discord
