For CP, I 100% agree with you. I had a match where our Grand Master Mercy player self-suicide (and only used resurrect while falling off the map), and when we were all going to report that player, he said "Go ahead, the reporting system is bullshit anyway."
Then we had another match where our teammate was a sexist homaphobe, harassing our female Reaper & gay Zenyatta players. While we were reporting the jerk, he laughed as 87 people had already reported him & nothing was done to stop his antics.
Players can get away with a lot, as they are not afraid of being reported. I generally wished the game had one similar DOTA 2's or SMITE, as you only have a certain amount of reports each week and it notifies you if action is taken/refunds the report since youre ostensibly using the system appropriately. Punishments range from chat mutes to low priority queue where youre forced to play a certain number of games only with other players that have been reported for toxicity/griefing. (Theres also a commendation system with similar limits.)
As you can guess, that latter punishment is rightfully seen as something to avoid.
