Why only the positive feedback? Why not honest feedback? Is not it means that you are buying fake reviews for your facebook page?
It's not a review.
When only the positive feedback will be asked I think it will go to untrustworthy. Better to ask honest feedback where people will post honest things that you actually have. So if there is no bad things then people will not post negative things.
I get the importance of having an honest feedback but when it comes to social media, it doesn't really matter if it's positive/negative. People will still criticize and bash you for paying users to comment.
~ I don't also think if there's someone will do that for just $0.3 cents.
Especially for 100 comments/feedback
OP, move your thread to the Altcoins marketplace since you are paying in eth.
