Facebook Jail? I've never heard it called that before Sam.
Block from posting or joining groups is a thing though.
When a block from posting or joining any groups happens though it's never permanent and only usually lasts a few days to a week.
It depends on several things. Some of these include;
- How old your account is.
- How many groups you are already joined to.
- How much you are posting/joining.
For new accounts
- Don't post too much too quick.
- Don't join too many groups at once.
- Don't post the same message too much.
- Use different accounts.
As your account matures and you are member of a lot of groups, over time, you will hit less and less group blocks.
I can post up to 500 groups in 1hour and be fine but that is old account who is already member of many groups.
Sometimes Facebook will lock you out and ask you to confirm your identity in some way.
See the thread I posted about that a while back.
They might ask your DOB, phone number confirmation, or to pick photos of your friends.
So make sure you keep details of all of that in case it happens.
If you need to post a lot then it does happen.
They lock you out though not in.
But only lasts for a while.
I got one earlier on a new account I was using LOL
I've had one so many times its comical but it happens less and less overtime the more groups you have and are joined to etc.
It's only when you do too much of one thing you've never done before that it triggers things.
