There are many stories and rumors that get distributed around the Internet. Many of them are untrue, but continue to get wide distribution because of their sensational or speculative nature. Stories related to the LDS Church or other “inspiring” incidents are often quoted in Sacrament Meeting talks or lessons as if they were true, in spite of their dubious source. Other true stories are modified in ways that dilute or change the meaning.
In general, it’s a good practice to be very skeptical about things you see on the Internet. Unless they are well-documented and come from a reliable source, be inclined to doubt them – especially notes that say “Please forward this to everyone you know!”
The unquestioning acceptance of things people “heard about on the Internet” is not a new problem, but it has received renewed attention with a current article on the LDS Media Talk web log. Another page you might look at is this one, which deals with some older but still prevalent LDS urban legends, and includes Church President Harold B. Lee’s classic remarks about the gullibility and sensationalism of some Church members.
