A lot of people here is doing this shit for years. If I'm correct, there are a lot of forum members who have been in this, and of course, there are reputed users who have written reviews for $5. I personally believe that it's dishonesty. But I don't think it's hated that much here.
Offtopic- You created this thread after almost two weeks from the creation of that thread which made me confused about what actually happened.
It is different from make use of my website, review it and I will pay certain amount of money. That is what I have noticed on service board that people do not against. But just paying for people without any review, that is a means scam can be promoted, because even people that do not go through the site to be fake or legit would have positive review of the site which might be used to illicit scam. I do jot like this idea, bit because it is not related to this forum directly, I do not see giving negative feedback to be appropriate, but that is just my opinion.
