Yesterday we saw a Dev from Valve address the community regarding a particular issue. There was a common misconception of people being able to report one particular person repeatedly. Gamers were getting tensed about the possible abuse of the system
However Valve Employee posted a comment putting many at ease :
I’ve just double-checked the code and also the database. It’s not possible for one player to report or commend another player multiple times in the same match. The UI may make it appear that this is happening, and we should fix that, because it’s confusing. But multiple reports in the same match are not being recorded.
EDIT: We’ve significantly reduced the rate at which reports are earned.
