I had a bit of work done (some stylesheets) on the internet and I paid the guy through Paypal. I had to add a new credit card and the payment didn't go through a few times because of currency conversion problems. It finally went through and all was well or so I thought.
This afternoon I got an email from Paypal saying my account access had been limited because they thought a third party may have been trying to access my account. I called them up and checked and it reall was an email from Paypal.
I've got to jump through some hoops to allow the payment to go through but it's very good to see that they are checking these things. It's makes me feel even more secure using the web.
