Revain platform is a blockchain project in the field of company reviews, projects, exchanges to games based on crypto currency. All reviews cannot be edited but will be added to the blockchain. Meanwhile other project is only talking about the idea, the revain has establish its own platform! But For me the experience of the user is the most important, so I will write my experience using Revain. Revain still has to fix the platform due to ongoing errors. Ai on the platform only works once in evaluating a review and then subsequently judged by the moderator. This is a good thing. But often members get blocks for no apparent reason. Even though the review was not a copy and paste result, Revain Team still blocked it and made the user lose a lot of XP. This is of course very detrimental to users who have invested time in writing reviews. While the team will not block the review if the review is just average. But often the review is blocked without a real explanation. If Revain wants the user to review and participate in developing its platform, Revain must provide a clear reason for each block that occurs. If not revain will be left by the user and will not experience growth in prices in the market. For me as a user and review writer, Revain must reduce excessive pinalty to its users. By giving a fair penalty, I think the review writers and Revain users will be satisfied with this platform.
