title: Is it reliable to use the IP address to identify a user on your website?
body: <p>Here is my situation. I am part of a project creating a P2P charity website, where users connect and can give money to one another. Because of the nature of the site, we know scammers are going to be rampant. We have several preventative measure ideas, and one idea that came up was tying an IP address to the user's account. The reason for this would be to be able to detect when someone from the same IP address creates several accounts. </p>
  
  <p>Would this be reliable? Why, or why not? I have been googling and found many conflicting ideas on the subject. Thanks for any help you can give.</p>
