Outline:
Circulating message purporting to be from Mark Zuckerberg claims that Facebook is set to launch a ‘no swearing campaign’ and that people caught using profanity on the network will have their accounts locked pending further investigation.
Brief Analysis:
The claims in the message are utter nonsense. Facebook is not launching such a campaign, and the message is not from Mark Zuckerberg. The message is just a silly prank and should not be taken seriously.
Example:

2014 Example:
As of March 20/2014 we at facebook will be launching a ‘No Swearing’ Campain, Anyone caught using profanity will have their account locked further a pending investigation.
This is due to the new laws issued by our legal department (section 182P34b) as new advertisers have petitioned for a ‘cleaner’ family friendly social network.
If a user continues to use profanity the account will be shut down and a permanent ban will be placed into effect immediately.- Mark Zuckerberg
