@Riot: Why is lag more of an offesnse than toxicity?

So I have a slow computer. Really slow. On medium graphics and no sound, I get 7-10 fps and 70-150 ping.

And occasionally my computer glitches on the loading screen. Everyone will be at 100% but the game won't start, so I have to close out of it and try again. This happened in a ranked match, and by the time I got back into the game, it was at ~6:35. I was mid against a mid . Enemy was super fed. I get flamed at all match, by two different players, one of which called me a troll, and the other kept saying "Report Aurelion for inting," while I was 1/3 and two levels up on our jungler, despite the jungler being there all game. When I asked "How am I inting/a troll?" I got no response, probably because they blocked me (who cares what the person you're flaming has to say?)

Of course, we lost.

I get 20 min leaverbuster, despite that game being my first afk in a while, and they get nothing.

Could someone please explain to me why players with slow computers/internet are more prone to punishment than toxic players? Thank you in advance.
