Not a showstopper. Same thing for cemeteries. All the owner of the presented info is trying to do is keep a commercial competitor from sucking up info they took the trouble to present. If you find an Aesswipe Smith buried in your family plot, this may be a big tipoff. It was so outrageously bogus that I thought all would get the satire and kill the topic.
Point is, consider the source.
Accept nothing at face value. I have also encountered people, who are well-meaning, posting incorrect and unsubstatiated information on gedcoms and elsewhere. I feel this could be corrected in some measure by requiring source information. Proof shoiuld be included. Otherwise, many researchers will be totally entangling trees.
