Hello guys. This account was made using my email, but it isn't actually me who made this account. Is it possible to delete this account so I can make my own account using my email?

change the email used to access the account to a dud one in the settings and give it some gibberish password, then make a new account

Hey man,you can't delete an account. Go settings,check if there is password,if not copy something like kdjfbbyug from here then paste it in both spaces ( you can paste,but you can't copy from there). Otherwise,ask Fizzer to ban this account.
