> The simplest solution is to just ban all user-visible metrics: # of likes, followers, friends, comments, etc. As long as on the server side things are sorted by likes and such metrics people will always go out of their way to game the system. In the early 2000's the original Counter-Strike game had a server browser utility and when it asked for a list of servers by default it gave them sorted by IP address. The result of this is that people would buy up and trade "low" IP addresses to be used as game servers. There will always be a system to game.
