Reminds me of the furor that erupted a few years ago when former Beatle Ringo Starr announced he was no longer going to be sending autographs out in the mail.
Not getting any younger, it turns out he was spending hours each week fulfilling autograph requests, only to see them being sold on eBay.
Kinda made him feel like an unpaid employee. Good he realised that in time to enjoy the rest of his life...
People will do anything for a dollar.
