So he didn't actually exploit?  Instead he asked the host to exploit (allegedly anyway, he could have been just taking the piss here or just been pissed off because of bad team play or whatever), called you noobs and talked trash?  That just makes him a pissed off dude, not an exploiter.  If he gave you an invalid gamestate, that would be exploiting.  From what you said he didn't do this.  There's no evidence here at all.

I do think it's the biggest problem area in the game when people can leave and cause invalid gamestate/critical error.

This is a long shot but this MAY be a guy who lived on my floor in college. He was epically bad at games, and not that swift in general, and we ended up making some sport of humiliating him. (Trust me he deserved it, he smelled horrible and would sit on your bed, leaving his stink behind, and stay way to close to you all the time, and put his hand on your shoulder or something if he was watching you play. He was unbelievable.) He originally used the name "star" in Diablo, and my roomate made an exploit mage named "starkiller." I would get in a game with star, give the pw to my roommate who would enter, descend through a portal I had left out of sight, and blow him away. He would get so frustrated, because he couldn't figure out how this guy was getting into secure games, and how he got down into the dungeon so fast. He wasn't that bright.

My roommate would also design Warcraft II maps that would say "Eff u (name)" in the mountains, and where the sheep would have 1000 hp, and he would adjust the unit stats so that the orc peons did max damage at max range and the humans did 1 damage at melee range. Then all of us in the know would select orc and have his slot preset on human before he joined. The game would start and the map would be literally covered with what were to him, invincible sheep, and we would watch as he hacked ferociously away at them to no avail. Eventually we would put him out of his misery by sending our one peon over to execute him from beyond his sight range. He was so confused.

Anyway, it may not be the same guy, but I certainly hope it is, because I miss those games.

Stupid school connection. Another double post.

My original point: people don't quit at cit collapse. 

A) He sucked, but has 76% win ratio

He quit at the exploitable time, but I think due to lag, was unable to pull off an exploit.  Him urging the host to quit near the end was odd enough.

C) LOOK AT HIS GAME LIST.  Go to page 2 and beyond.  Literally half the page is "incomplete" and the other half "win". 

D) Listen to his bullshit: "The other people dropped on me in those games".  Really?  All those "wins" you got, they didn't drop, but the other half of the games that would normally say "lost" for nearly everyone, says "incomplete" for you.  According to the averages, he's saying the opposing team drop-exploited instead of just winning and every game SStarkiller WON, the losing team took it like a champ.

Take it for what it's worth, but I wouldn't let him in your game, he's willing to wreck it in the name of his "ratio".

And no, the "hall of shame" is not that great.  Not updated, subjective judgments, and nobody checks it.  IMHO, better to put out a warning and perhaps our special case will stop cheating if he thinks he's been caught.

Put a screenshot of this mythical page with HALF incompletes. the most any page has is 3, most have 1 or 0. If you think "N/a" is incomplete, you're misinformed, N/A is when the game lasts less than 3-5 min and doesn't count. Check out the times, if you honestly think i managed to lose a game in 2.5 minutes, then exploited to have it cancelled, ur on drugs, you don't need to exploit, if the game ends in less than 3 ish minutes it automatically doesn't count. As i said in my previous post: i checked and in the last 5 pages of games theres SIX incompletes, SIX, thats about 6 out of ONE HUNDRED GAMES. that is NOT a lot of incompletes, and can be easily attributed to the game being buggy and crashing, not caused by anyone intentionally and the other ones would be when other people did it to me. I usually get 1/20 games have people on the other team who do that invalid gamestate. Maybe im unlucky, but even if his accusation were true, 6% lower win % would be 70. 70 is still really good, if i was genuinely horrible at demigod and only managed to get win % by cheating, id need WAY more than 6/100 invalides. check and mate, noob. oh and btw if you want to 1v1 me ill wipe the floor with you, and prove that win % is deserved.

I already proved he was full of it, that half of my games are incomplete, totally bs. I only challenged him to a 1v1 cause its so fun to beat arrogant noobs.

Quitting during the citadel does not invalidate the win/loss, eh?
