The instance list at joinpeertube.org includes whitepositive.media, which advertises itself there as a white supremacist website. This is a problem because the main join page for the peertube project is actively promoting Nazis. This may present a legal problem in some countries. Additionally, it seriously undermines the credibility of the project and will discourage people who dislike Nazis from joining any peertube instance. This will lead to lower participation from several groups of potential users including racial and ethnic minorities, LGBT people, feminists, leftists and people who object to racism. This combined population of lost user base is larger than whatever users one might gain on Nazi instances.
For my own part, I teach in a university and would like to steer my students away from youtube, but absolutely cannot link my students to any website that is promoting white nationalism - including yours.
Please excuse the length of this post. Your promotion of Nazis is dismaying and upsetting and I hope very much that you quickly correct this problem.
