Under the fandom Hermitcraft SMP is the tag "Ethoslab/GeminiTay (Hermitcraft)" and also "EthosLab/GeminiTay (Video Blogging RPF)"; the latter tag is also under the Video Blogging RPF fandom where it should be, and the disambiguation IS the canonical one, it also generally refers to the IRL YouTubers as opposed to the characters they play, so having it under the non-RPF fandom tag could cause some confusion!
