We now select videos on YouTube as ‘Unlisted’ for a number of reasons, these may include…
1 – They contain copyright music so can’t make money via youtube ads.
2 – They are either age restricted by youtube, or we think they may need age restricting (This is NOT adult content, youtube age restricts for the pettiest of reasons), and so we cannot make money via youtube ads.
3 – We may think we have enough similar videos already on youtube, so decide to set it as ‘Unlisted’ instead of not uploading it.
4 – Sometimes we think it would be nice to set a particular video as ‘Unlisted’ just for the hell of it.
