UNFAIR PLAY! THIS SHOULD BE REPORTED!

This game- Modern Chess - NoVabbeSeiUnGenio vs inom17021984 vs EndgameAssassinXpert vs bukvoj - Play Chess Variants Online - Chess.com 

Red and Green in this game are actually trying to not let me capture their pieces and this is not fair! It's so annoying, and second- they can have a pre-arranged team where they play team, not FFA!
I have reported this game. Please tell me if this is a valid report or not! 
JUST SIMPLY UNFAIR!

In the first stages of the game, it is usual to team with the opponent player to rapidly eliminate one player. It's a strategy that usually pays off later.

But not that- my opponent red is preventing me from taking green's pieces!

Keep in mind that red was weaker than you all, so another strategy is to temporarily play together with the other player to play against the strongest one on the chessboard, otherwise you would have won.

bro ur 2200, u should understand how this works

Were you playing as teams ?

He probably didn't know he was on a team

No, he was playing FFA, but it seems he didn't understand some dynamics of this game.

Yes there are two brothers who talk in different languages and win by cheating

There is no issue here. Prearranged Teaming is illegal; teaming is perfectly fine....I can help who I want.

I assume you are talking about 67.r & 66.g. There is nothing about those moves that suggests the teaming was prearranged. Green was under threat and needed to get your queen away, so 66.g makes sense. 67.r makes sense as well; it isn't prearranged teaming, that is the best move for red in that position

To clarify, prearranged teaming would be where I communicate to another player off-the-board (in chat for example) that I am going to help them.

Teaming is where I decide, without communication with the other player, that I am going to help them for some period of time. Strong players do this all the time, but there is some element of risk because there is no guarantee that the player you are teaming with will reciprocate.

I don't see you think this is pre-arranged or cheating. As @HSCCCB said, I assume you are thinking this because of 67.r. If you are talking about any other move(s), I looked at the entire game and to me this is the most likely one you are talking about, and even if not what I am about to saw still applies.

First off, look at red's point of view. As their queen is protected by a rook, nothing bad can come from this for them, if you decide not to take red's piece. If you do, it means that they are the only player on the board with a queen. Therefore, this looks like a perfectly natural move to me (though maybe confusing to a beginner). From green's point of view, they are in pretty dire straits with a very open king and seem to just be trying to delay getting checkmated and/or getting as many points as possible (though I don't know why they didn't take your bishop instead, but likely they predicted red's move)

Second off, if you consider working with another player to be cheating (or that working with another player in any way is cheating), then by that metric you yourself are pretty suspicious! For example, look at 36.y. You check green, meaning that green gets to take red's queen for free! Pretty sus, eh?

Disclaimer: The last bit was sarcastic, I don't think you are actually cheating, I am just trying to show you that a player helping another player doesn't necessarily mean they have pre-arranged to team up

1st thing - It's the skill...they are teams they work together... obviously they won't allow you to capture their pieces because they have a plan (Maybe)

2nd thing - OBVIOUSLY! THEY ARE TEAMS!
