I am sorry but I disagree.
A couple of years ago a huge amount of devs were spamming links to games on groups and make FB pages for those games, unfortunately, more than 90% of them were garbage and facebook noticed that so in the current day you either work for your exposure and engagement (like I did in the post above) or you pay money (funny thing is that I found trough my latest experience is that making free marketing on Facebook brings more engagement than paid marketing on Facebook).
Don`t hate the player, hate the game.
