What made people sick of Facebook was pages upon pages of Farmville, Mafiaville and other games. And still, I get new game invitations by the day from relatives and work colleagues which I unfortunately cannot unfriend.
When I used to use Facebook, I was able to block those games.
Not only can you block those games, you can prevent individual people from sending you invites from any game without unfriending them.
When you close an application invite, there's an option to "Ignore future invitations from Firstname Lastname". This maps across all apps.
You can unfollow them.
Yes, but it's like with the underground markets... ban one, another appears :/ I'd like a "Make FB useful, ban all notifications from all apps tagged 'game'" option.
I haven't received an invite for a game in months. Yes, months. Facebook also does a really good job of filing them under Games folder/label which I don't visit since I don't play any of the games.
