Is dSero Anti AdBlock for Google AdSense a scam

Describe the problem you have found and a link to the spam:
https://drupal.org/project/dsero_anti_adblock_for_google_adsense

I have contacted the maintainer on Facebook.
I was interested in seeing a demo of it in action.
They couldn't provide one and I told them that I would look for a different solution.

Until now I had not received any kind of spam on Facebook, ever.
A few minutes later I received Nigera connection spam.
It's highly unlikely that this was just a random bot.

The question is if their business practice is this bad and their plugin just being a sales pitch
for their "service" should it be listed as a valid drupal module?
Since all they're doing is collecting email addresses to send spam to and selling them off.
