i am an outsourcing person not a programmer and i am working on shopping website like ebay , so my question might be beginner for everyone.my website will need a user suspension in case he violates the terms and conditions. here is some thoughts on my mind: -IP address tracking -User information ( email address or any information are going to be repeated on second time of registration after suspension) -session Id cookies are also a way to identify the users after log in

any more creative suggested ideas to avoid fraud and scammers, it it possible to make 100% impossible to avoid those bad users from coming back ?
