Lagging results

If people are lagging and don't want to anything is that fine? I mean I was lagging and I didn't want to feed or anything so I decided to sit at base. If I go in while lagging i would just die a lot and get reported for feeding anyways? I don't see how riot handle this fairly considering that people actually lag and riot gives them ban or whatever they give to that person. And the league community is really bad please nerf it >.
