There is not a freedom of speech
Chat rules in four player chess

The rule is that you can't be abusive. There are things that are obviously OK. There are things that are obviously inappropriate. And there's a grey area in between.
And the lines might be different in different contexts. Some things that might be inappropriate with strangers you might be able to get away with in a group of friends.

lol you easily can be hilarious to each opponent if you wish considering what's been displayed here and call it reverse psycology.

I don't like chat in FFA. You shouldn't be able to discuss/promise future moves and strategies. Its collusion 101. Take Poker for example. The rules there are good. One player to a hand, no extraordinary abuse (cussing or just being a cuss) and English only while in a hand. NO SAYING "if you raise, I'll reraise and we'll squeeze somebody out." Lets take all of yellow's pieces. Let the game stay on the board, out the chatroom.

@Squishey,
What is the result of your swearing? Will your teammate become a better chess player if you call him a scum? Will you become a better person by calling someone a scum? Will you save a lost game by calling someone a scum?
Swearing this way is usually a sign of a low IQ (or a sign of a spoiled schoolboy). If you want to look stupid just continue to swear. People with high IQ use irony and sarcasm instead of stupid trivial swearing, or just keep silence (because they understand people are not ideal).

Actually the link between swearing and intelligence is often misclassified as negatively correlated when is it completely without empirical basis for a non socioeconomically disadvantaged demographics, in fact many studies shows that in fact could well be the other way around. One such study shows clear link verbal fluency as a mechanism for this habit and the need for an individual to put in emotional impact with a degree of effectiveness. http://www.sciencedirect.com/science/article/pii/S038800011400151X
If anything trying sound super deep and ironic and a clear sign of pseudo intellectualism stemming from deep seated emotional insecurity over ones own intellectual capacity resulting in this overcompensation to be a "tryhard" and be extra sarcastic and smart in comments over the Internet with strangers.

Those questions come from an inherent fallacy that any action must have a utilitarian purpose or goal driven directive that is in anyway meaningful. My goal can simply be to increase the level of dopamine in my nucleus accumbens which any proponent of postmodern nihilism can argue is just as meaningful and noble of a goal as trying to save the planet or prevent global warming.

You should look up the definition of contradiction. Nor do I confirmed that was my goal at all "can simply be...".

If swearing increases the level of dopamine (in your case) then you will swear even if there is no reason. And you will not accept any arguments. And even will find a pseudo-evidence (like that sciencedirect.com article) to justify your behavior.
P.S.
By the way, that article is about the active vocabulary of a person. It does not say anything like "the link between swearing and intelligence is negatively (or positively) correlated". And it is obvious that a person with higher IQ knows more words.

Did i say there's no reason? I said it doesn't matter what the reason is, in case you can't read between the line.
Speaking of pseudoscience, you randomly bought up an unempirically supported correlation between swearing and intelligence, when clearly many confounding variables could be at play (socioeconomic background), which btw even if supported (which it hasnt been) does not universally apply to everyone in that category (thats not how statistic work). What's even more amusing is your assumption that it's supposed to have any effect on another's behaviour (oh stop swearing, if you keep swearing it means you have low IQ, so don't) clearly is not how casuality work. Not cussing isnt going to increase ur IQ (only ur percieved intelligence to psuedo intellectuals) nor is cussing going to decrease ur IQ if you are already confirmed to be have highly superior intellect.
@BabYagun whats ur IQ? Are you very smart? Is that what you are trying to say? Are you saying you're smarter than him? Are you a genius? Do you use sarcasm alot? Is that why you are so proud?

Intelligence aside, why not just try to be nice? There's way too much hate on the internet and the least you can do is to not be a part of the problem yourself.

@Squishey, I think you do not understand that I show you a mirror here. So you can look at yourself.
First of all, what did you expect when you asked your question? Did you think people will tell you: "Yes, please call me a scum and an idiot. And then whip me harder!" And then Chess.com admins will join and confirm that you can swear like that. Seriously?
About the link between IQ and swearing:
1. It does not matter if there is a real correlation. It is important what people believe in. If people believe that "swearing is often a sign of a low IQ" they will think and act accordingly. (It is like those myths about coffee, apple cider vinegar and avocado.)
2. I told you about the IQ, because you do care about "what people think about my IQ". As a confirmation I can show you your posts and even topics on this forum posted here to show people your IQ. Just 2 examples: "First 1500 in team mode" and "Current problems with Team Mode and potential improvements" The first is a crystal pure "show off" topic. The 2nd was created just to tell us (quotation): "As one of the top players of this new game mode ...", because all those 6 suggestions were suggested by other players before. So, the topic is about "I am a top player with high IQ", not about the suggestions actually.
3. And that would be acceptable and even funny. But you also do not miss any opportunity to swear and humiliate other players. For example, look at https://www.chess.com/clubs/forum/view/got-a-good-win A lower rated player shared his idea. @brian_daniel373 said "boih aint nobody care about yo 1230 games". Guess who could not be silent? Of course @Squishey supported @brian_daniel373 by a creative "Like" sign.
How many times @Squishey did you tell "You have no skills" to other players here? Is it a trolling? Balm for your ego? Both?
Just a mirror.

> whats ur IQ?
I do not know my IQ level. And I do not care about it.
> Are you saying you're smarter than him?
I am trying to say that swearing makes @Squishey look stupid and childish. At least.
> Is that why you are so proud?
Proud of what exactly?
P.S.
At first I did not understand why are you aggressive and ask those questions this way. Then I opened your profile and found that @Squishey is your friend. Now I understand
I've been getting complaints from snowflakes all around so I wanna ask what are the rules regarding four player chess chat, can I say anything as long as it's not racist/sexist/homophobic?
Can I call someone out for playing like a coward or a scum?
Can I berate useless partners for being idiots and ignoring my advice and not playing the winning move?
Can I rage at useless players for timing out and costing me a game?
Can I trash talk at all?
Is there freedom of speech?
