So if I understand correctly, just the fact that our name, address and email address are on a list somewhere, doesn't mean that fraud can be committed. In order for fraud or some type of crime to occur, we must be contacted by someone trying to commit fraud by posing as a legitimate business, person, etc. Since most of our information is already online in databases, we should be vigilant in researching and confirming requests for information by mail, phone, or online. For example, if Paypal or your Bank, or anyone else contacts us and asks for passwords, account numbers, etc., contact that business directly via the phone number that appears on your correspondence from them.
Yes, scammers and crooks and all types of evil are everywhere.
So, while you may hesitate to sign an online petition, you can contact ebay to express your opinions regarding selling of puppies directly if you have a facebook page by using these links:
