got account deleted for no reason?

im so sad ive had my account since 2019 and ive put hundreds, probably thousands of dollars at this point into it. so first my sister went to go play roblox and her account was deleted. before that my brother said his account was deleted but i thought he was on an alt so i didnt think much of it, turns out it was his main account. so now im freaked out and i check mine and its also deleted. like hello? what did i do like am i not allowed to build my house in bloxburg or something?? also i semt an appeal and they like denied it so am i screwed or can i get my account back? also cant find the ss of the email but still..
