Interesting, but its based on user generated input, so this data could easily be manipulated by someone that doesn’t like particular games creating a few accounts to add bad data.
It could also be manipulated by someone who reports the dark patterns are inaccurate. If it were run by a single org or person, it could get sold to a company interested in gaming the ratings or used to bash things the owner doesn’t like. I’m not entirely sure what your point is. Every way to set this up is subject to bad actors. There are some checks and balances present in the website. Why are they inadequate and why should we not trust this site? Are you, perhaps, an industry dark pattern plant trying to get us to avoid something that could deter dark pattern usage?
