In the last week i've seen several examples of false information being spread on social media, like a virus. It's ironic it's spoken about as something "going viral."
Some "friends" that should know better just seem to be making bad decisions by sharing and starting to believe the crap that's out there. It's more likely to be fear and anxiety in some cases, but we all know, don't we, you can't believe it just because it's on the Internet.
