In the results list of Videos search, when you click the "Raise" icon (for example), it says "This site is boosted in your results." regardless of which platform the video is hosted on, but only Youtube channels get added to the video personalized results.
If the video is on a PeerTube instance, Vimeo, Dailymotion, TikTok or another platform, the domain name of the website is added to the "regular" personalized results instead, not taking the channel / user into account, even though their name is properly shown in the results list (only Youtube ones have a link to them, though).
I expected the channel / user of the video to be raised/boosted and added to the video personalized results list.
A way to raise/lower a PeerTube instance could be interesting in addition, but way less important than having it for channels / users.
