Occasionally, when I am signing up on a site where I want to be a paid member, there is a message on the sign-up page that says something like this: 'Your IP address of 123.345.567.789 has been logged. We will prosecute all instances of fraud."
Is the IP address really that useful for finding a user in case of irregularity? Should I be storing a user's REMOTE_ADDR in my database when they sign up? Especially if the monetary amounts involved are very small?
Thanks for any insight.
