I checked some of them at random and personally, I wouldn't label those as proper reviews [or as you mentioned "honest big reviews"] but instead, product listings with their descriptions...
- A proper review should contain your own personal experience with those and AFAICT, that's not the case [sorry if I sounded rude].
Proper reviews? For over the years, any review page with regards to any projects, airdrops, cryptos, are automatically discouraged by tons of users that experienced reading faked reviews and faked review sites partnership as most reviews requires initial money to be promoted on such pages. And even if the OP promises an honest review and he even experience it all, the image of any review websites remains the same. How come? I can simply reach you out and offer you huge sum of money or shares, would you not take it? If you are talking business, then I guess whatever it takes, you will accept it.
Dear OP, I guess it is better to rather establish trust and provide the real honesty first. Be like the Cointelegraph but for lowkey coins and airdrops.
