It could appear like that on a new section on your profile, and on the actual movie/tv show pages it could maybe appear at the bottom, where the you might like X recommendations are now at. and if there are no recommendations use the ones currently from tmdbs related movies/ related tv API.
They also offer what Trakt currently has a recommendations: named favourites. Those are your (current) favourite 10 anime, 10 manga, 10 staff, 10 characters, 10 production companies. For paying members, you get to pick 20 entries per category.
I was a VIP for a month or three, so I have 13 anime as favourites
Posted this in a different thread, but since @lifeiscrazy gave me a hint. My idea:
I think Trakt is great. I use it for both anime and western shows. I do go to Anilist when I want to discover a new anime. Why? Because users can add a show recommendation to a shows page (Example: Spy x Family) and users can vote thumbs up and down (You have to be a user for 2 months or something) and so I can find a lot of really good anime which looks like the show I have searched.
Although the recommendations system has become better, something like Anilist would return much more better recommendations!
