Obviously, there are so many fake autographs out there whether, eBay, auction houses etc. Some will be sold intentionally, some innocently.
My question is do you bother to contact the seller and tell them? What drives you to do so? And, if you do, what sort of response do you get?
I ask because I see so many - and have been wrestling my own conscience about whether to flag them up. I'm no expert (new to this), but even I can spot a lot of them ...
