I find this an interesting comment. If you in fact had such documentation and it could help restore some large portion of people's confidence in your integrity, wouldn't you make it as public as possible?
Well, yes and no. Let's say you've got a bona-fide donation and it checks out to a reasonable certaintude with what's been posted over at AV123. I would expect, reasonably I think, that the donation to have been made on behalf of AV123. If it was made on behalf of MLS himself, his wife, or step-daughter, then that means he also used the donation to offset personal tax liabiilities. Now, this might not matter to some, but I don't expect the individuals of a company to profit from the kindness of others.
Further, at this point in time, anything you put up as a picture indicating what you've contributed is going to cause additional scrutiny by people. Like me. If it's fake, that could be subsequently used by agencies as Exhibit XYZ.
For a man who loves showing pictures of his dogs, of production in Colombia, etc., what great PR, and justifiably so, of him handing over a check to a Red Cross official in the state of Colorado, as well as the sundry other raffles he has run.
Oh, I also want to see doctor's notes.
