Why not also add a check for a temp cookie? That would maintain itself on each computer regardless of the dynamic ip change, but would have to be unique per machine.

Give it a period where if it switches back from one temp cookie to another too quickly, you knock out one account, keep the older active. Keep doing it.

bump, update!

Just use their web form to block your site and you are done as far as sharing accounts is concerned. Though there will likely be more services like these.

I need something like this as well and I will try to work on something to detect this soon. :mad:

Hello,

Just curious if anyone ever developed this or is working on it. I am a webmaster for a site which requires subscriptions in order to access the content. I'm looking to make sure that a username is not being shared between multiple people... I found this topic and was hopeful something like this already existed. If it doesn't exist I would even consider a paid request.

Have you tried 'multiple login detector'? might help... sends an email or a PM to admin upon one person logging in with different user names, might be a key there

That's the exact oposite of what I'm looking for. I don't care of someone is logging onto the site with multiple usernames as that means they are paying multiple subscriptions. What I'm consider with is a user who pays a subsciption fee, then gives his buddies the account info so both of them can log into the site at the same time. I need to be able to protect against multiple people using one user account. Not one person using multiple user accounts.

Right, yeah... ok... then each user must be uniquely identified using ip addresses perhaps, if the same ip is used with the username & password it works... different ip...same username & password... no entry! - but there's a problem with that... many users have shared ip's and ranges... hmmm

Which was discussed previously...

So does anyone know if this exisits or is willing to create it?
