What happens there is that the dev simply deactivated the account as a "creator" which means that he will not appear as a creator but as a simple member, but all the original content of his account is still there in case he ever wanted to reactivate it, so the patreon staff still has access to everything that had been published there "posts, links, images, polls", meaning that if they find something they don't like they delete the account, which means that the dev if at some point decided to come back or start a new game he would have to do so with a new account.
Maybe this explains it better
