Stop being insipid.
Do the wayback yourself, you wouldn’t accept anyone else’s work anyway.
I would believe your work, if you showed it. Instead, every time you’re asked for proof, you either ignore the request or deflect (e.g., saying that this has been ‘verified’ because Mike Adams is ‘reliable’).
If the Google cache shows a pre-shooting date for this site, it should be easy for you to post a screenshot. So, go ahead.
