Fortunately, there is a cure!
Joking aside, I really find it annoying when people blindly share posts that make great claims, while neglecting to verify the information before they post. You know the posts: little Susie has cancer and her parents cannot afford treatment, but if you "like" and share this picture, $1 will be donated to her healthcare fund. Or, Facebook is going to start charging for access. If you "like" and share this post before this date, however, you won't be charged! Well guess what? Facebook is not going to start charging for access, and if it was, it would be a site-wide notification, from Facebook administrators. Oh, and you're not donating any money by liking or sharing a picture, because it is just not a function Facebook offers... you're simply spreading sadness by exposing people to heartbreaking tales that are either not true, or years out of date.
