Disconnects

I do not post on this forum ever but recently I have been running into a reoccurring issue that I don't think riot is doing enough about, in my games as of recently I have had people who's internet is not up to par with the requirements to play this game. If you disconnect or afk due to an internet issue and it happens rather frequently then you should be temporarily banned and eventually permanently banned, I understand the argument that it is not their fault and they shouldn't be punished for it, but on the flip side why should I have to lose elo and the chance to practise in this game due to someone else's internet issue? thoughts are appreciated thank you for reading.
