Those only expire after weeks. It's unlikely someone can't attend to it for that amount of time. Just using favourites as something to address later seems incredibly unfair to the author/artist. When they are told their work has been favourited they don't think that it's been added to someone's to-do list, they think it is actually a favourite.
"If all mankind minus one, were of one opinion, and only one person were of the contrary opinion, mankind would be no more justified in silencing that one person, than he, if he had the power, would be justified in silencing mankind."
