I wish people would understand how common this is. There's no customer service line you can call when some overseas moderation farm worker spends 0.8 seconds looking at something and taps the hotkey for one of the reasons in their terms of service that they deem an account should be permanently wiped for. Have some recourse. Buy a NAS that will do automatic backups of all your cloud accounts. Long ago I lost a decade of Gmail and GDrive because I posted a PNG file of a credit‑card form that said "This post only viewable with Google+ Gold." You need to be treating these accounts as ephemeral.
