we do not have NSFW Alternative Instances

And honestly, I get the impression that even most threadiverse users aren't using peertube. The content creaters you know and love are on YouTube, and it's a significant time investment to sus out which peertube creaters are interesting to watch. Plus I vaguely remember that the last time I tried using Peertube, the website(s) itself wasn't great; I think it was a mix of bad performance and unfamiliar and possibly not-as-obvious-as-you'd-like UI.
