Ping spamming

I just had a game where Vladimir pinged like crazy for everything. EVERYTHING. Including ping spamming our Rengar after he died mid in a countergank. Pinging his dead body. What does that even accomplish besides annoying your teammates?

When we asked him politely to stop, he only spammed more pings.

Like, I get that smart pings are useful, but people like this only make me hate this 'helpful' system.
