Twitter Jail is no tweeting if you've reached the limit

of 100 tweets per hour/1000 per day.



You can access your page, you may not post publicly

for a specific period of time. Anything from half an hour to a few hours.



Sometimes people refer to TwitterJail is someone get their account

suspended. This can happen for various reasons.



If you are stuck with your account you can also use Twitter Help Desk

and submit a support ticket if you cant access your account:
