Ask the staff directly via Help & Support
Why Chess.com 22nd Tournament organizers allow dishonest players?

Right. That way, this problem will not be aired in public. Feh.
Well if you just want to bellyache and accomplish nothing, just keep on doing what you're doing now.

Thanks for your answers. I'll post it in Help & Support, although I think that is nothing wrong airing this problem in public.

SORRY, I meant click on Help & Support at the bottom of the page here and contact the staff directly that way. The "Help & Support" forum is mainly for members to help each other, the staff doesn't look at more than a very small fraction of what's posted there as far as I can tell
There's nothing wrong with discussing this in public, but I sincerely doubt that it actually accomplishes anything. At least complaining to the staff about specific cheaters (or suspected cheats) puts them on the staffs radar, and also gets them kicked out once they're caught.

You can air the question in this group & may receive advice:
http://www.chess.com/groups/home/cheating-forum
Is open to anyone to join.

Thanks Nimzo and netzach. I followed the indications of Nimzo and contact directly to the staff in http://support.chess.com/Knowledgebase/Article/View/124/0/cheaters--cheating-what-you-need-to-know .
There is indicated that "Fixing game results by playing with multiple accounts or losing intentionally is also considered cheating", so the report is already done.
If something happens, I'll let you know in this forum and I'll post my experience in the cheating-forum that netzach said.

Don't count on the staff taking any action against this player. I had the exact same situation occur to me. Guy blatantly lost 20+ games to the same opponent on move 1. Lost 200 rating points in a single day. I called him out on it and he blocked the chat. I reported it to cheating staff. Nothing done and no info would be divulged on the investigation. Guy has continued the behavior afterwards.

I can't be bothered reporting the player again. If staff took the complaint seriously, the player would be on a watch list and action taken when he repeated the behavior. I get the feeling if you have a paid membership, you can get away with blatant abuse.

hmm. Well I don't join the official-tournaments anymore. They do seem to attract the worst mischief.

And yet you can be bothered to whine to us about it.

Yes at least the my forum mates give me a decent response. Thx for letting me vent. I feel much better now.

It's really unfortunate... if a tournament is about to start I try and keep my rating as healthy as possible so I get to play the hardest games, therefore most enjoyable... I'm not naming anyone here but I unfortunately know a few people who deliberately drop rating points before a tournament online, and someone who even does it otb. It's all very sad and pointless, all I can say is you know you're a genuine and honest player, let that thought be enough to overcome someone sad enough to throw away a few hundred Elo just to beat players they already know they can beat... pathetic. Knowing this, I always enjoy my games, and if I get destroyed by someone 200 below me, and it does happen a fair bit lol, all the other games I play can/will/do make up for the poor loss.
I signed eagerly in the 22nd Chess.com Tournament, but I found that a player in my group is a cheater and this has disapointed me a lot, and probably there are many others like him in the tournament.
This guy had and average of more that 1900 ELO point during last months and just one week before the tournament, he lost some games in just one move and his ELO dropped 400 points. Unfortunatly he's now in my group.
If this dishonestity is easily identifiable, I'd like to ask the organizers why this behaviour isn't punished (for example with disqualification).
I signed to the tournament to enjoy with other people this great game, but also to give my best to win (to win against my peers) and not to lose the opportunity to classify to the next phase due to a dishonest player 400 ELO points stronger than me.
I hope for future competitions can be implemented some measures to avoid these drawbacks.
