Tried it two times in the last 3 months with a FB page... failed both times.
Its a 50/50 deal, sometimes it works - other times it doesn't.
If we're talking about spam ranked parasites that's the same experience I had. In fact, there was a very clear window of time (late 2014/early 2015) where I was churning out and ranking FB properties 1 after another after another like cake. I went to take a 2 month break to work on local sites. Came back to FB and nothing fucking ranked anymore.
The "evolution" I personally saw was:
SB +YT - Back in 2011-2012 guys were blasting AA lists and ranking parasites for terms like "how to clean my mac" (pewep was one of those guys lol). Then GSA came...
GSA+YT - GSA works, but eventually YT is devalued, hundreds of thousands of YT videos are swiped off page 1. G does this to strike back at spammers.
GSA+FB - This further proved YT was the problem, and not GSA links. Right up until G released another update that neutered GSA links.. and tons of parasites got hit.
PBN+FB - I saw a surge of FB pages flow onto page 1 now being backed up with PBNs rather than GSA.
PBN+.com - Spammers realized the whole point of parasite spamming was to leech authority from strong sites and rank using SPAM. Not PBNs as once you start doing that you create a huge opportunity costs. YTF invest / build a network and point authority links at a FB page? Cause that page will rank a few months quicker? But you don't control that page? Fuck that. Makes more sense to rank my own .coms. Anyone who was following a lot of keywords this was what I saw.
There was a FB rebound after YT, then a shift from GSA to PBNs, then eventually from parasites to .coms.
There are still tons of ways GSA ca be used. And PBNs. But parasites in general are making less & less sense. I just don't see many parasite spammers on G these days doing much of anything other than the movie method. Which is a shitty, brutal, 3rd world method.
In all seriousness Tommys parasite guide is one of the best on here. But if you spend a lot of time these days just looking at G.... dudes have mostly abandoned parasites.
