It can still work well but you can't only be doing f/uf anymore. If using some form of automation, you are better off maxing out all your available action types. That means follows, likes, comments, story views, story likes, emoji reactions, etc. The limits are starting to decrease across the board so if you were relying solely on a singular action type, you won't get the sort of gains that you were getting last year anymore. Gotta evolve alongside the platform. Limits will likely increase again after the election cycle is over tho, had the same thing happening back in 2020 as well.
