Searching for #PeerTube in #Bing and thus #DuckDuckGo gives zero results. Bind mentions that "The search result may have adult contents has been filtered." and that "age verification is required". While DuckDuckGo just shows zero results.
I understand that there might be PeerTube instances with adult content in the search results but I don't believe all of them have adult content. I know mine does not.
