Check user GUIDs

  • I’m running a WordPress site that has giveaways. It randomly picks from the WordPress users that have entered and it rewards them. However, I’m trying to figure out how to make it so that I can access my user’s computer GUIDs so that I can ban people who have multiple accounts.

    The trouble with IP banning is that people use proxies to bypass the security system.

    So, is there any plugin or custom code that allows me to do this?

  • You’ll find it very hard to do this because that sort of info is not available. For a bit of info, have a read of this. The only thing that you have to work with all the time is the IP address. The problem is that there’s really not much that you can do to stop people from doing things like this. It sucks, but people will always find ways of getting around restrictions like this.

    Some years ago I was on a website which tested how track-able was my web browsing, it turned out that between my browser add-ons, installed fonts, versions of this and that, than my browser was unique among all that had visited.
    You would need to gather lots of this info using javascript. Hope this gives you some ideas.
