My last use of Rakuten was 3/21/2013. Edit: Upon looking a bit more, I noticed I did use Buy.com on 6/4/2013 that went on this credit card, but it was through PayPal, so the number should have been protected from that.
Your $1.00 PayPal charges appear to be Credit Card Verification attempts by PayPal. It could be the same for Yahoo Wallet and possibly "RN". The fraud-artist appears to have setup a new PayPal Account with your credit card and PayPal is doing their traditional card test. None of those charges would ever appear on your statement since they cancel out. The only way to see them online is to expand the section on "Pending Charges". It's a great way for the fraud-artist to test a card before either selling the card number or using it for a purchase.
