That was partly the problem. I hardly ever use paypal & it was linked in almost redundant email account that I only check once a month at the most. That was the reason they went undetected at 1st. It was only when I checked my bank account that I realised something fishy was going on.
Paypal detected the missue of my account (albeit too late to stop the funds clearing), but of course, they sent an email advising me of the fraud to the email account I never use. DOH!
I've learned quite a bit from this experience.
The final kick in the teeth was that paypal refunded the money into my back account plus my banks fraud department also refunded the money. So I actually ended up getting paid back twice the amount that was stolen.
I've never been fairly good with money & never realised I was paid twice, so I ended up spending all the money, only for the bank to ring me one day & explain they messed up & would be requiring the overpaid amount back by the end of the week
