It's bullshit. Claptonstring is the web alias of someone namend Daniel Velez. Back in 2015 he had already tricked someone here (Matt?) into sending him a lot of money for outtakes and demos of the 80's/90's he doesn't even have.

That was the message being sent around back then via fb to warn other Jovi fans:
"Please be aware there is a fan by the name of Daniel Vélez from Columbia claiming to have hundreds of out takes and demos that he is willing to sell for the right price. He’s taken advantage of some trusting fans recently and will send you a fake .rar file once he’s been sent the money.
Web aliases include Claptonstring and Claptonpick, he tried this scam on ebay as well.
If you have any information on this or have been tricked by him in the past please e-mail joviscammer@gmail.com, any help would be amazing.
I can provide a list of the fake songs he’s offering, send me an e-mail."
