Hello
Is there any way to perfectlly avoid users to register into a website twice?
I already know that we can avoid dplicate username , emails but this is not my question.
Example: website WWW is a forum website and allows user to register by allowing the users to choose their username and enter password. this is good. Website WWW also configured her website that duplicate entry of user name and email is not allowed.This is very good. the problem website WWW is now facing is: a user "A" that already registered with WWW can still register with another email address and another name. can this be avoided?
Website WWW now try to store user IP address and used this to screen the user from registering twice. but this can only work if the user has static IP not dynamic IP.
can we get maybe the device name the user is using to connect to the website WWW? or mac address? I understatand that this can be violating privacy agreement if the user did not allow permission for WWW to access her device name or mac address.
Is it possible to build an application that will prompt user to allow WWW to get her device name or mac address to avoid duplicate registration in WWW?
these questions are complexer as I thought
Any Idea?
