I've been spectating this player a few times. He's obviously a troll. His movement is basic, he rarely even attempts to shoot, he will suddenly stop moving mid map (even if he has the flag) and then do weird movements like step left/right, turn around a little and then move again after a while. But often he just idles on the limit of being kicked for idling, meaning he surely knows the timer and when he gets a warning he moves enough to not get kicked and then idles again. If this isn't team sabotage I don't know what is and I find it absolutely inexcusable that nothing is done about this player despite numerous continuous complaints about him.
He will ruin every 2:2, 3:3, 4:4, 5:5 game. If the server is full then it doesn't make a big difference as better players will compensate for his lack of playing, but with less players having him on the team is a huge disadvantage and makes a lot of people angry as it ruins one team's game. I've played with less skilled players and while it can annoy me sometimes, at least I understand that they're trying their best and in my book that's totally fine, I'm average at best. But sapito (or whatever nickname he goes by) is not even trying. It's not like he suddenly needs to go afk, he does this all the time. And he's not kick voted most of the time because he's a handicap only for one team, opposing team won't vote and some people just don't care about voting.
