We created a new Twitter account for testing purposes, and the odd thing is Twitter never actively asks for your birthday in the first place, despite warning you that it has a minimum age limit of 13 years.

To add your birthday you need to go to Settings, Your Twitter Data, enter your password and then scroll down to and click on ‘Add your birth date’ next to Birth date.

If you attempt to put in a birthday with the year 2007, no warning will pop up suggesting you’re doing anything wrong, but when you next try to click off that page you’ll get a message saying your account has been locked.

How to unlock your Twitter account

To unlock your account you will need to click here, then supply photographic evidence of your actual birthday. A driver’s licence, passport or birth certificate will be ample.
