We avoid matching players who are rude or abusive with those who are kind.

I was wondering how this is done. Are there some lists of players "rude / kind" ? If I want to switch from one list to the other (guess it's more likely to start as "kind" then turn rude) so it would be from rude listto kind list, is this possible?

lol yep

Spoken as a true smart ass. Very good.

I always reckon if the knobs are blocked they'll all end up in thier own little cesspool of players and can wish cancers on each others families in comfort.

You can't go from rude to kind.

Real simple: block them after the game.
Isn't this just common sense? 

Actually there was a post about this a few months ago; should have bookmarked it.  Anyway someone was curious about whether such a "bad player" pool even existed and through a series of deliberate disconnects and timeouts in losing positions managed to find himself in said pool.  He said it was populated by some of the worst people he had ever dealt with.  But yes, by playing "clean" for some number of games he was able to escape back to the regular pool.

That pool was just made up to calm the people.
It never existed. It was never explained by a staff member on how it worked, and it could simply never be carried out.
How would they move the people where they go? By IP address? By linking their account to the pool?
How would they know whether the person in question just has the most terrible internet connection ever, or using the app while having a few other app open (that causes some godawful lag)?
Chess.com gave no information about how this system works, which means it's simply not true.
Because if they did it without giving any information of it or having it written down in the terms and conditions, then that's just simply illegal. 

Of course it doesn't exist.

Are you saying Chess.com would deliberately lie to us?  Oh, the horror...

Seriously I don't know anymore than you do, but I do know that there's enough legal loopholes in the TOS (Legal, down by the green pawn) to let them do whatever they want.  So no, it wouldn't be illegal.

Who said it's illegal?!

I assumed that a change like that would be serious enough as to at least inform the users of it.
I mean in theory they'd get actually transferred to other pools. That, I consider something to be of importance.
A warning sign, let's say, that actually states what happens after what action.
Whatever, maybe I'm just too naive. 

Gosh, there are only the three of us posting here.  If it wasn't me and wasn't you...

Yikes! Sounds a bit like a creepy near-death experience.

Well I assumed that actions taken against users without informing them about it in some form is considered 'illegal'.

And here is a link to someone who claims to have experienced the pool first hand.  I believed him...

And it's all I could find:

Chess.com encourages players to be kind and show good sportsmanship. Our Fair Play policy expects that players will not...

• intentionally disconnect during games
• stall to make opponents wait unnecessarily
• frivolously abort games because they don't want to play black, etc. (Note that we have now implemented a limit on the frequency with which users may abort games; please Abort only when necessary. Also see below.)

If your account is flagged for habitually breaking this policy, your play will be restricted, requiring you to wait 5 minutes between games (including aborted games).

There is no mention of any pools whatsoever.

You're looking in the wrong place.

We also try to avoid matching certain pairs:

        • We avoid matching players who have poor internet connections with those who have solid connections.
        • We avoid matching players who frequently just disconnect or quit without resigning (aka "Fair Play") with those who finish their games properly.
        • We avoid matching players who are rude or abusive with those who are kind.

I stand corrected.
