Go to the bottom of it today thanks to a very quick email reply from Paypal.
Apparently it's a spoof site, I need to report it using a link they supplied me and they will get it shut down.
I now need to change my password to Paypal and log back in via a new link the Paypal person gave me.
As said above, NEVER ever give your PIN to anyone. Hence me checking, and thankfully not having my account drained by some robbing twat
Sadly, this sort of thing would have "got" someone like my mum and dad... the site looks 100% genuine, and to be fair if it wasn't for asking for the PIN, the rest looks almost reasonable.
Be careful out there folks
