Within Destiny you can report players. At first I thought this was for only negative feedback but after using it to report someone for a negative thing I found out that you can report people for positive behavior as well.
I searched around and was unable to find whether any amount of reporting (good or bad) actually has an affect on the players you're reporting. If anyone knows what the implications of the reporting system is I would welcome the information.
I am playing Destiny on the PS4.

It's been rumored that during a game, reporting a player for a negative reason will decrease your likely-hood of seeing the same player again, (possibly not at all) and reporting a player for a positive reason will increase your likely-hood of seeing the same player in the event.
It worked that way in Halo, made by the same company.

So I assume that a player report will be directly read by the support team, not entirely ignored.
It may also be possible that a player might be elected for a moderator if he gets a lot of positive reports.
