It seems to me that one of the main points in the study of UFOs and other paranormal phenomena is to separate outright fakes from possible real messages. Do you have any personal clever ways that help identify real cases so that you can study them more closely later?

Previously, for me, such criteria were a large number of witnesses, real physical traces and as much detailed information about the case as possible.
