joinpeertube.org is not family-friendly
Any person can go in here instances.joinpeertube.org/instances and unintentionally click on a instance that has NSFW content, this is not family-friendly. On instances.joinpeertube.org/instances should be shown only instances that don't have NSFW content and then have some settings menu that will allow you to view instances that have NSFW content, if one wishes so. Thanks you.
