Bugs, false positive and real corruption?

This plugin is a mess! Not only it is an open door for spammers to subscribe, MANY bugs are old and never corrected. The only reply is “get the paid version”.

Additionally the coders post false positive feedbacks, and it is very strange that many negative feedbacks are simply deleted by WP censors. I suspect that at least one WP moderator has close connections with the plugin team. Or receives … gifts to wipe the negative comments!
