I think this downvoting is not that absurd. Hahaha :) Its really useful anyways.

Just accept that no feature here in AFF has no downside. Not everything is perfect so just look on the bright side.

PLUS, authors can only do it if a person in their comment box of their stories is rude. I think it serves right to those people who doesn't know how to appreciate the story they are reading and why read it if you don't like it? YOU MAD?!

Just be optimistic and don't think of things as of trollers. Why the heck would you comment in a story that you know is awful and not interesting. People have their rights and those rights should be used but don't abuse. 

The main thing I'm saying is don't comment if you don't like the story/chapter/plot, etc. It helps not to be greedy for karma.

Disclaimer: This is only a opinion about the downvoting especially an eye-opener for those who think putting this feature is a bad idea. PLEASE DON'T BASH ME I HAVE FREEDOM OF SPEECH
