I also used them for years, then everything blocked and deleted instantly. I have other homelab type friends, same thing happened. Again more anecdote vs anecdote. But if you google about hetzner and this type of activity there are bagillions of reddit threads.

After paying them about a grand a month forever, losing all my "safe data" and having to wait a week for even a response that just says "account has suspicious activity. Disabled". Not a single response after that. And they had the nerve to charge my credit card again at the next payment period. Overall, truly scummy. And I will prevent everyone I can from ever engaging with them.

When hiccups happen, you would hope to be able to at least talk to someone and figure out what's going on. If they don't want to keep your business, fine let me get it out privately. But they don't play that way.
