A Facebook post claiming to protect users' photos, personal information, and other digital property, has yet again been making the rounds on the social media network. But does sharing it actually work?

The post typically reads:

In response to the new Facebook guidelines, I hereby declare that my copyright is attached to all of my personal details, illustrations, comics, paintings, professional photos and videos, etc. (as a result of the Berner Convention). For commercial use of the above my written consent is needed at all times.

Bottom line: the post is a hoax. Posting the message above on your Facebook page will not protect your posts.

Facebook doesn't own your posts, but under its privacy policy, they have the right to distribute and share your posts, depending on your privacy and application settings.

Also, the Berner Convention doesn't exist. Whoever first wrote the post probably meant to write the Berne Convention - an international agreement that protects literary and artistic works.

Instead, check your privacy settings and make sure they're set so only people you want to see your posts can see them.

Or, you could share this message as an alternative:

Facebook will begin stealing your underwear at midnight tonight if you don't copy & paste this message in the next 37 seconds, forward it to everyone in your mailing list, print a hard copy for your grandmother & call your first ever nursery teacher. This is real. I got the message first hand from Elvis who was having lunch with Bigfoot, while riding the Loch Ness Monster. It was even on the inside back cover of every tabloid in the grocery store checkout line, beside the nude pics of Prince Harry!!!!
Not only is this above going to happen, but Facebook will start charging you tomorrow. They are also going to bill your credit card for the past 3 years of services. Luckily, each person who copies & pastes this status will receive a FREE Rainbow unicorn in the mail tomorrow. However, if you don't re-post this status, Facebook code has been set up to automatically set your computer on fire. Remember: copy and paste! Simply sharing will NOT save you from your fate. You have been warned.
