In reply to Giorgos Sarigiannidis.

I don't know; the abuse possible only grows by adding negative feedback, to plugins or reviews. It's been my experience that most every plugin has it's fair share of 1-star and 5-star reviews, and half the 1-star reviews are clearly from users who just didn't get it, expected one-click-magic, etc.

I think of it like Facebook and their likes and reactions. Still no dislike button and there's a great reason for that. Negative feedback indicators are prone to false reporting from angry users, whether or not their anger was unfounded.

And even still, I find that too many plugins in the repo are deserving of a "Scam" button. They often don't do what it says, or the author uses misleading language/flat out omits where the line is between freemium and pay-to-play functionality. It would be abused, but perhaps the answer the to negative feedback is to track the user who leaves it. Something that is seen by mods and authors that attaches even a modicum of accountability.
