I think the commenting via disqus on bitchute and it's mirroring of youtube have helped it grow quite well, yes. I've been using social networks since the early days and I know what it's like to use a network that has literally no censorship at all. If the right people come together, I learn a lot from others and people are interested to read and comment what I produce. As you point to, I get next to no activity on Youtube and I have proven that they sandbox/block my comments often. We are going to just have to leave them to become the internet's 'prison TV' and do what we can to help the world understand that!
