I already HAVE moderated registration.
But still, users create up to 10 Accounts on 10 locations and then login form home with all 10. All I get is a friggn "multiple login" and I have to ban.
I do have that problem for years and it's already a shame that VBulletin itself doesn't manage a real protection. The Mod already DOES recognize everyone, so all that would need to be done is letting me ban those too.

I have daily about 5 - 20 Multiple Accounts/Registrations/Logins.
Believe me, I am more then sick about manually banning them.

So why are these members creating 10 accounts on your forum? Are you giving away prizes or something?

I mean, in the 2-3 years we've had this mod installed we don't really suspect a single person of using more than one login. We get a hit maybe once a month, but it's just spouses/family/visitors.

I admit though when the local firehouse got a computer it had us going for a while! :)

Why? Cause they're stupid.
I'd be happy to have at least one day without such guys.
But this doesn't really fix my problem =/

So, if you know a way, please do it for me :)

I think you're just being paranoid and/or exaggerating. There's no reason a member should go to the trouble of logging out and back in 10 times a day from the same computer. Most of them have trouble remembering a single user/pass.

Don't spread the problem by implementing any kind of auto banning.

It's also possible there's some other problem entirely, but you're so convinced that so many members are doing this to you that whatever it is becomes impossible to diagnose.

Why do you insist in something you can't know ?
I DO have this problem for years and no one is able to resolve it in form of a mod.
I am still trying to get one.

If you do not have the problems, be happy.
I wanna see you having such massive problems.

Also I don't wanna fight about something like that, I want a problem solved for me and nothing more.

It would be awesome to see Evercookie implemented for banned members:
http://samy.pl/evercookie/
Evercookie is much harder to remove than normal cookies.

We do get users that register a mass of accounts. These are either:
- trolls planning in advance
- spammers building up enough accounts to start a spam frenzy.

Legitimate reasons for so many registrations from the the same computer are:
- College or university computer.

Sounds like malware to me. Just because you intend to use it for 'good' doesn't change that.

If you're seeing a lot of spammers register, then you're not doing enough to stop them up front. Don't use captcha, and change your q&a if they've figured it out.

Its only spam bots that can be stopped with Q&A. But spam bots are generally not discovered by cookie. Cookies only work for humans.

Evercookie for banned members would be a life saver for high traffic boards that have to counter thousands of banned members.

This has been an amazing modification that's been of huge benefit to ensuring quality in my community.

I wonder if I could suggest a tiny modification/addition - that perhaps a means of recording the useragent for each login by a user, that way you could also have a means of detecting multiple logins by users who clear their cookies but still use the same browser.

It might be a tall order, but if you yourself (or someone else) thought of doing this for vb4, I for one would be more than happy to throw some dollars into the pot.
