"It is possible for inaccurate information to be submitted for reasons including, but not necessarily limited to the following; a false positive (a test resulting in a diagnosis of a sexually transmitted disease when in fact the person does not have the disease), a fabrication by the person inserting the data, a false rumor, an inaccurate published source, or a false statement by a third party. Since false listings are possible this site does not assert that any person listed does in fact have a sexually transmitted disease or that statements made about them are true."
Could it be that someone contracted a STI and posted the person whom they possibly contracted it from? Sure, I guess. But could it be someone who is angry and wants to post a completely false accusation, or isn't sure at all, definitely. The website even acknowledges that. No medical basis. No fact. No good.
