According to the owner, they are currently adding new sites, and they are manually reviewing those casinos. They will later check those websites by playing and testing withdrawals as well. Also, when they launch the 2nd version of their website, users will be able to report anything, such as the website is not operating, scam, or other things.
I found this initiative as unique. I haven't seen such website before. So, I expect them to stay around and I think I will be one of their regular user. I hope they won't close the website suddenly.
Honestly that seems like a lot of manual work! Also spending this much money without any profit doesn't seem right. In the future it would be hard to keep up with the expenses without any revenue generating from the site. They must need some sorts of sponsor or ads to able to survive.
I don't believe them to be unique in any way. Similar sites already exists and even better. For example casino guru. You can get all the information you need from that site. So my question is why would user want to use a site that only offers a little much information? I understand they are new and in their beta phase. But without in depth information it would be hard for them to attract visitors.
