bunch of cheaters in this site

345678910 Are the admins supposed to be monitoring thousands of games here simultaneously? I think not. You can complain about suspected cheaters directly to the staff here, I presume they'll start watching someone after getting "x" of complaints and maybe their anti-cheating software also automatically picks up on some cheaters, but this is only a guess on my part.
Could you pls provide some evidence that "almost everyone here +2300 are cheaters?" or are we supposed to just take your word for it? Although it is nice to know that someone who joined 2 days ago is already so knowledgable about this site.

What's your hurry here's your hat - don't let the door hit you on the way out - come back when you have less time to visit

You should contact admins directly as Nimzo suggested (http://support.chess.com/Knowledgebase/Article/View/124/0/cheaters--cheating-what-you-need-to-know) - mentioning it here won't accomplish anything, make a report as per the instructions on this link.
