Offtopic: PayPal shares more than we think it does. I've had issues where certain merchants asked me to confirm identity by sending copy of utility bill for address I had on PayPal account. I thought my address is private so sent a bill for my siblings house where I also paid the bills for internet, but they reported that address is not same with PayPal, so I argued a bit but eventually had to send one for correct address. I think that, PayPal doesn't share CVV but merchants can view all personal info attached to my PayPal account.

That doesn't seem too weird to me. Wouldn't most merchants necessarily have your address in order to provide services to you (shipping would definitely require it, for instance).
> I once saw a pdf which listed all the third parties that PayPal shares its information with. It was more than 30 pages.
What kind of info do they share with those third parties?
I think the GP's point stands, since the "unknown third-part[y]" that customers are usually most concerned about is the merchant, which Paypal definitely doesn't share payment info with (like CC numbers).
