I guess these reviews can only be posted by helpers, and these helpers undergo qualifications before they can be appointed being a helper, so let us call that filtering process, and saying negative review as long as they have proof about it will never be biased and will help customers a lot and at the same time making the product owner to enhance their service and make more quality products.
So it means reviews written by common users to a certain business company are being filtered and approved first before it appears on their profile?
Why would they need to hide a negative review? If this is the case the transparency is useless. LINA review is not about positive reviews. It is about using blockchain technology, qualifying the reviewers and giving the most reliable review on the market. Only when companies learn to accept criticism that they can grow. As for the common users review this may also be reflected but I think the helpers review will be used in rating the product being reviewed. Again, blockchain technology helps us trace the source of the reviews but the main thing here is hiring qualified reviewers, HELPERS, based on their qualification.
What could be the main purpose of Helpers? I mean are they are the one moderating the Lina.Review's website?
Moderation is a helpful way to enhance the reliability of the lina review. It can ease the review fraud.
For the moderating part, that would be the community: helpers, users, the helper board and the devs/bug fixers. The system is community based, user based, exact review system will depend on user configuration. They already said there will be a like/agree button, I believe there will be more.
Anybody can be a helper actually, now its up to the individuals of how they are gonna do it or apply in actual. It can be for a good or bad purposes, but in the end they are both moderating the topic in the thread. However if we are going to base it in the whitepaper explanation, the reviewer can become a Helper if the the help board approve it but if the helpers fail to comply their responsibility they will be demoted into a common users.
