Here I will add teams, that are 99% obvious cheaters, and that have been not PUNISHED. And offering you to add also teams of same "skill invite" with description.
1)
Audere Semper eSport.PL
http://www.cybergamer.org/team/74229/
Played versus them
Match Time: 21/1/12 - Saturday 11:30PM CEST
www.cybergamer.org/matchdetails/187545/ there you can find their demos.
I didnt make any timestamps, because didnt want to waste my time.Admins rejected my dispute and didnt even open any demo according to rule:timestamps missing. So we have lost them 25-15. After our match they played versus STYLE'OF GAMING
http://www.cybergamer.org/matchdetails/187851/ and looks like scared to use hacks versus style, because I opened dispute versus them immediatly after the match. They ofc lose , with big score 25-9. Hm... Funny thing is that we played versus STYLE'OF GAMING and won them 25-22
http://www.cybergamer.org/matchdetails/186498/ Match Time: 18/1/12 - Wednesday 9:50PM CEST

And to finish cool story
I found on my pc nice screenshot of 1 pracc, we played before versus this poliaks, hm the score is quite different
SPOILER: Click to view
13-4 (Match Time: 09/10/11)
Looks like this poliaks learned how to play just for 2 monthes playing cod.pracc.
So my advice, dont play versus
Audere Semper eSport.PL
