I just found my PayPal account has all the addresses that I have in my Amazon account. I am completely spooked.
It's okay. I put them in there for you...
Your HSBC account is safe (your RBS one OTOH...) ;)
:snark: dammit this is serious :'(
PayPal is a subsidiary of eBay and it isn't a valid form of payment in Amazon, so that seems odd, the obvious question is if you don't recall entering the info in PayPal.
Why don't you call them and ask? ::)
I'm too scared to phone them.
The only address i've entered in PayPal is mine.
It's possible they log the delivery address entered on a site when a site gives the option of paying by PayPal, but the addresses ares ones I've only ever used Amazon for.
The possible things are foreign cookie reading (low level) or a common corporate partner sharing information (high level).
In both cases they may be trying to subvert your privacy in the name of convenience, and not in a necessarily nefarious* way.
