Honestly, people who just move a little to stay then stop for most of the match in the game shouldn't join a lobby at all. That's the main problem with this, Nintendo should definitely be harsher on those who don't play the game as intended, I mean Smash Ultimate will kick self-destructors from matches, so that's a good thing. Now to just make it require more than just moving a little to be able to stay in the match for Splatoon would be so much better, although not perfect, still much better than having game throwers running free.
