[Client] Riot, Can you please remove the Friends of Friends invite feature? Or at least adjust it?

Since the last patch I received multiple ninja invites from people I don't know about because they just click at every person in their friend of friend list.

I can understand that some people want to invite certain people without giving them invite rights, for reasons. However, can you at least adjust it that we can only see their friends when they're in the game lobby?
