This would be wise to pass on to Snopes etc if they are unaware at this level. Is there anything in the graphics which might reveal what system, etc. it was created upon?
We do want to be careful about false witness against a neighbor, however. That’s basic Christian conduct. It should be noted as a controversy rather than a proven matter until thorough investigation is done.
Why? I have no confidence in Snopes, etc. Any more than I have confidence in newspaper "political fact checkers".
