I had my Paypal account hacked a couple of years ago, they were actually real cool about it. They put all of my money back in a couple of days.
Somehow a hacker got my password and emptied my PP account, buying Starbuck gift cards. I called them, they froze my account for a couple of days and then put every cent back.
Lots of guys bash PP because they are anti-gun and sure, they take a cut of sales, but I still use it for the convenience and great customer service. If I ever had a question about a transaction, they looked into it right then and there and resolved the issue or let me know everything looked good.
As for anti-gun, I enjoy the irony of selling gun stuff on PP.
One thing of passwords, hackers get a ton of them from forums. If you install a ad blocker and java blocker you will see them light up whenever you are on a forum. Your info is going everywhere. I used to use the same login and pass for lots of sites, one of the forums I am on was hacked and the next day my Hotmail, amazon, credit card and shit even Walmart accounts were locked from attempts to login. Just be careful and make very strong passwords. I run a Mac now; never had an issue with Malware or viruses, but Apple loves to collect data and tries to be sneaky about it.
