Is there a way we can prevent users from sharing accounts. I have a subscription site where a problem I have is group buys where 5 or 6 users are using one account.
I think by using sessions against cookies to check if one user is logged in from one location might resolve the problem and admin is to be notified if multiple sessions are detected for one user name. Can we check it against user agents aswell.
Basically I want one user to use one account and not 5 people sharing 1 account.
How difficult to create this mod?
