AntiAlt A incredibly simple antialt solution. Currently in beta
This plugin is an AntiAlt solution that can restrict the maximum amount of accounts from a singular IP-address to a given value. This means you can keep an eye on alt-accounts and largely prevent alt-abuse.
The plugin is based on the confguration file to determine how many accounts are allowed for each IP-address, but as exceptions always exist you can also set the amount of alt-accounts on a specific IP-address.
Please note that this plugin does not focus on preventing VPN's! Check out this free universal antivpn also from me by clicking here.
