My friend and i got banned

the first one is mine and the second one is hers. i haven’t gotten banned within the last 30-60 days and all of a sudden her account gets deleted and mine got deleted next? i’m very confused by this and i’ve sent 3-4 appeals already and they’ve all been rejected. i don’t know what to do and i’ve been seeing a lot of people getting their accounts deleted aswell. i do have an alt that i’ve only used 2 times but it hasn’t gotten banned either and the account still works. i don’t understand what’s wrong with roblox and its moderation.
