Why not? I guess they are also interested in making their product (TOR network) cleaner and without scams. I think it should attract more users to the whole TOR network. The only my doubt is that the TorProject.org decided to support Hidden Reviews recently. I see you are new here but I can say that Hidden Reviews are here for a couple of months and just now the TorProject decided to support them. I don't say it's strange or suspicious but why did they not do that before when the devs have announced the project to the community?

Maybe the devs will give us some more information? hanswer?
