Extra reportable offense: spamming
I was in a game just recently where my own teammate would be incessantly pinging me, doing it when I died, or doing it when I missed an ability, or just doing it when they died and I couldn't help, and etc.
Under the reportable offenses I could find that the only real option that I could consider relevant would be the 'harassment' option. I'm not really sure if that is sufficient because when someone spams in chat or particularly with pings, the whole team suffers. At least with chat spam you can mute the player, or just ignore them (especially when the spam/flame isn't directed at you) however when it comes to ping spamming, the whole team has to deal with listening to it.
I understand the need to keep the pings audible since it is a very important aspect of communication (and even an asshole can properly ping to prevent you from getting into danger) I don't feel like simply having 'harassment' as the only option for ping spam as a sufficient enough category. When you ping spam, you make everybody suffer, and that should be taken into consideration as it's own unique form of harassment separate from the type of harassment that you can just mute and ignore.
I'm not talking about muting the pings, but I'm simply talking about an extra category for reportable offenses that really reflects the impact that ping spamming has on the team.
