It is idiotic that "hearting" an actor/actress on their profile page yields no benefit whatsoever. You cannot access an automatically compiled list of these individuals. In other words, the intuitively obvious thing to do has not been done by the developers.  What if anything is the purpose of such a site if not to keep track of your shows, movies, and favorite actors? To keep a list, you have to create one yourself then manually enter their names one by one. Extremely tedious. Seriously in 2020?

End rant.

I think if you look on the Suggestions Forum, there is a suggestion to add an option to follow actors. You could go upvote it.

Yeah, that a great point. Thanks for bringing up the suggestion post. I'll go upvote that now.
