"El oh el reporting in ARAM? Noob"
You can get sent to Tribunal because of it, so I don't know why people pretend that you can't.
Show them otherwise. Report them for their obnoxiousness. After their first warning they'll feel really silly.
Just keep reporting them. I've seen less of the stupid "custom-games reports don't count" nonsense than I used to but it's still around.
This is my personal tribunal for only ARAM games. It happens, and it makes me report these toxic players every time.
