As we all know spamming game request (e.g. request tickets to continue stages in Candy Crush) was almost a MUST in popular games, but nowadays less and less people are actually paying attention to these annoying notifications in Facebook (at least I do and blocked all of them). And, I don't see any trending games doing this anymore (e.g. Clash Royale). Should we still spend time implement it or is there a good way to do it?
