I don't think so? Unless something changed recently that site wasn't even federated with anything, it was (is?) just it's own standalone website. In the beginning the dev/owner couldn't even decide how to display posts/conversations & changed the display format a few times.

I remember for a while the dev/owner would use throwaway Reddit accounts to spam his website every time people were discussing Reddit alternatives, like "hey you should check out this one, it's great!" sort of spam. The spam was enough to turn me off from creating an account there.. and realistically it didn't look like it was going to gain any real traction.

This stuff about the owner going alt-right is news to me, it's been off my radar so long I never bothered checking if it still existed.
