I came to the conclusion after making short research, It looks like I found a part of the answer to my question: The blockchain-based Revain review platform has announced a partnership between Revain and DragonEx. They will implement the new reward system which will send the reward per high-quality review.

I've been in this market for years. I don't think there is much need for a platform for review especially recently. You can find a lot of content on Medium, Reddit, Twitter and many other social media channels.
Why would we need more platforms just for this?
