Excellent plugin

I love this plugin that frees us from unfair payment systems, which make us pay fictitious subscribers that in the end we can not remove.
I have tested it with more than 100 thousand subscribers and it works perfectly.
It would be great if in the future you could add the possibility of recognizing subscribers by countries.
To know the reach and amount of clicks for each campaign.
To be able to eliminate the users that do not visit us in the last 30 days.
Thank you very much to the creators.
