I see that most contests (i.e. I think at least 90% of them) have fake virtual participants in the top spots (this is pretty easy to see given they submit all the problems within 10 minutes). Not major, but it looks bad when most people actually take virtual participations seriously and don't want to turn off seeing them. Maybe they should be devirtualized. MikeMirzayanov
