My friend was using a public access computer at a local racetrack .After he checked on something on "Ebay" he was bidding on and then looked at his "My Ebay" section where he had to log in listen what happened. He even logged out of the Ebay account but some kids still got access and he goes home and a couple days later he gets all these e-mails saying "You are the winning bidder and owe X amount of dollars" etc. etc. And I mean a lot of items he realized it was kids because he is 40 years old and all the bids were for teenager type CD'S and toys and games. What a mess that was for him and how long it took to finally clear up everything. So I highly agree, be CAREFUL
