"Much ado about nothing".
The basic question is: DID THEY SIMPLY COMMENT THE GAME WITHOUT POSSIBLE INFLUENCE ANYMORE (even during the game), which is pretty legal (cf. the chat rules) and that I do as well, a lot, or DID THEY DISCUSS FUTURE TACTICS OR STRATEGY TOGETHER, NEGOTIATE, PROPOSE, SUGGEST SOME COMMON ACTION?
I've played with all 3 of them more than 500 times probably, I do not think they are cheating (but yes, at least one of them is just unpleasant).
I know these players Carlos Gabriel and Luciano well, and they are not cheating players. They are players who are contributions and promoters of 4pc.
@SPatrik If you have a complaint of this type, you must make reports through the normal designed means, they cannot occupy the forums, to make complaints or public protests.
