When my account expired, I had only 2 pageviews, 1 of which was my own.
The page was only 3 days old.
Since then, I actually did create a fake account which I use every day to try to “communicate” the problem to facebook, but nothing has happened, I don’t think I’m getting through to them.
I did around 100 likes by then, not knowing if there was a limit.
I would think in the scenario that you went through, FB would have deactivated the account.
My account is clearly not deactivated since I know what that warning looks like and since, when I’m in the fake account, I can search for and see the group I created in the real account. Mine is expired, whatever that means.
