1. You can make a command using the command variables like so: @lookupinfo@[@l_followdate@,@target@]
A more advanced version that either tells if they are or not: @if@[@lookupinfo@[@l_followdate@,@target@]||||@target@ is not following the channel.||@target@ is following the channel since @followdate@.]
2. No not really, unless you manually move followers to a VIP group, then you could. But you can always use the "active chatter multiplier" or the "users must have typed something within the last x mins in chat to earn points". Both settings can be found in the Config Tab > Master Settings > Point Options.
