Now I'm not exactly sure how to put it, but at this time it seems to me like it should finally be considered.
Especially since Nessie (Real Vinyl) has been using Nessie watermark on all of their videos for almost a year and a half now, and all of their official pages, including [Twitter](https://twitter.com/UtterNessie), [Patreon](https://www.patreon.com/TheRealVinyl), [SubscribeStar](https://subscribestar.adult/nessie) mention the exact same nickname.
So, my suggestion: reverse the aliases and make artist:realvinyl the alias of artist:nessie.
