My question is: For webmasters, how do you prevent fraud from your website, what steps do you take to prevent: 1. Duplicate users signups 2. User is using emails like yahoo and so on 3. user is able to change IP probably by a proxy and thus he can sign up again and provide fake info any other fraud prevention info is welcomed! Thanks, Rob
yes 1 email address and 1 ip addres but i am more concerned about the third... also some other things i will do: 1. manual aproovel. 2. user must enter all his information. 3. get a proxy list and ban it's ip's any one knows how to do the third? if any one can answer my partners question it will be great:
Ask paypal account info, ask full name & street address... ask them to make a $1 credit card payment (it's a small sum, yet it's pretty good way to ensure where the money comes from)
