I sometimes receive warnings for verbal abuse without speaking,
and it's great that Riot's making sure people are informed when they're reported. It's cool, because I know the report'd get discarded by the system. I can't be verbally abusive without verbalising anything.
However, I'd like it if the system went the extra mile to tell the reporter, "Hey bro, I just discarded your report because while I get you were pissed off, that's causing your report value to go down."
Sometimes I'm that person who's so pissed off I report someone who's done nothing wrong, and sometimes I need that reminder that I'm just being a pissed off dick and shouldn't report people for bullshit. It's also a good thing to be told when my reports are discarded as bogus reports, because when I know that what I perceive as toxic behaviour might just not be toxic behaviour ("GG, EASY GAME"), I can calm down and stop getting my panties all in a bunch over nothing!
