1. Facebook has permission to use your photos and videos for whatever it wants.

Have you ever wanted to see that awesome sunset picture you took or a funny video of your cats in a Facebook ad? No? Well, too bad, because when you sign up for Facebook, you give it an expansive royalty-free license to use anything you post that could be considered intellectual property.

You still own all of your content, but Facebook is allowed to use it and give other people the right to use it, too. The only way to revoke the license is by deleting the content from Facebook.

If it seems out of line, it’s actually pretty commonplace among other social media sites. Twitter, Instagram and Google all have similar clauses in their terms.

2. You can’t use Facebook if you’re a convicted sex offender.

This one is pretty straightforward. If you’ve been convicted of a sex crime, you aren’t allowed to register for Facebook.

3. You’re required to keep your contact information up to date.

Facebook requires all users to keep their profiles updated with any changes to their contact information so it can make sure your account is kept secure. While it doesn’t specify a timetable for email addresses, the terms say you need to update your cellphone number within 48 hours of making the change.
