Totally not fair
THIS IS NOT FAIR!

I get the feeling some of these persons are very young doing this. To them it's funny and entertaining while not having ANY RESPECT for the game. In the meantime, we can't have a fair elo score because of these antics.

@SupremeDude100324 Teaming is a way that they often uses to win, I have been teaming like dozens of times, that just normal.

I suggest chess.com to create a group game. 2v2 is ok and the person in our team cant cut our items. As a 4 player chess player with 1600+ rating I also felt it.

Cooperation is okay. when one player is winning the other 2 will usually gang up on them in order to stay alive. Blatant teaming where no matter what they will help each other and do this over the course of multiple games is reportable, so is causing you to lose on purpose, but only to cause you to lose.

Dude in FFA ok, two of the opponents are friends, they are guiding each other and checkmating me and the other. This is not fair. I have reported but chess.com is not looking at the case. Why is this? If anybody can help me with this, I would be grateful to you.
Teaming is wrong in ffa.
There is no strong fairplay policy for ffa but if chess.com confirm teaming in ffa and they have strong proof then both the accounts will get banned.

I think in FFA it's only ok to team with your opposite but you can't communicate with them in chat or with arrows, it's a tradition of mutually agreed alliance at 2000 FFA or above

Not necessarily. You know what is good for a player and what is wrong. You can play supportive move for anyone player whom you had teamed up without even chatting.

I know such things as I faced many players teams against me and many times when a high rated player join a loby of weak players then all weak players teams up to defeat that high rated player and then they make their own game after knocking them out

Has happened to me before, They teamed in chat and I am dumb enough to forget banning chat.
