Toxic Players and Spam Pinging

I understand that toxic players are inevitable, and that the pinging system in LoL is fundamental to the way teams must work to successfully communicate objectives and win games. However, and too often, there is one person who is acting up and obnoxiously flaming in chat and spam pinging mia on corpses (toxic spam pings that have no objective value). I usually try to keep my team un-muted, and I usually don't have a problem when muting people is necessary, but it starts to feel very ridiculous and distracting when the troubled person I've muted continuously spam pings on top of me. I also understand that the option to remove pings (visual and audio) would have a negative impact on the game, but I believe something should be done about this; something beyond simply having the ability to report players after the fact. I prefer not to mute pings (and I know the visual cannot be disabled), so it can become very difficult when I am trying to focus on a play or a fight while toxic teammates spam ping MIA question marks on me. It is genuinely distracting, and once it starts causing me to make mistakes and give up leads or fall behind, the 30+ minute match becomes unbearable. These are usually the same players who die once in lane, stop trying and lightly feed, while throwing up surrender votes at every opportunity. I'd at least like for something to be done so they wouldn't bother me with spam pings. Like I mentioned, I don't think introducing an option to disable pings would be the correct solution, but I believe there should be some thought toward a solution from the development team.
