I agree with you redcat, we are in the same situation
Few months ago, i received an notification, and when i accessed my cpanel, there was an option to protect my account.
I didnt understand. It wasn't inactive. But no problem, i just click on the link and everything was ok.
But now, on last sunday, i tried to access my site and i was redirected to a 000webhost page error. When accessed cpanel to see what happened, it was just cancelled, no option to protect, no notice, NOTHING!
And it wasn't inactive again. I sent a ticket support just 7 days ago, and maybe, accessed cpanel some times after this.
And my site was accessed everyday by a lot of people.
I would like that an admin told us what 000webhost considers INACTIVITY.
They just say "sorry we can't recover"
Sorry for bad english
