Jungler-hunting is such cancer

I can't be the only person out there that thinks intentionally hunting the other team's jungler is unsportsmanlike and frankly just cancerous. So many times, and usually by a foreign lee sin player, do I go to play jungle (my favorite and normally best role), and get absolutely fucked by being hunted. No, I don't mean counter-jungling, I mean the other player doesn't farm, doesn't try to push objectives, but just sits in bushes and waits for me in my jungle, to do nothing but kill me and take my mobs. He doesn't gank, he doesn't do his jungle, he sits in mine and nukes me as soon as I respawn and come back. No matter how many times I call out that hes gonna be there, my team doesn't help, then flames me for dying again when if I leave base, I'm gonna die. It's unsportsmanlike because he isn't forwarding the game in a productive way and is intentionally just trying to ruin the game for myself and others who have had this done to them. It's fucking absurd. I normally don't get upset at video games, but this shit has me unbelievably upset. There's no countering it if you're playing alone and you get flamed by your own team as well.
