Nice post.
Player stalling in hopelessly lost game -- chess.com will do nothing about it

The OP's opponent hasn't broken any rules except for the vacation abuse, chess.com is fully aware of this. This will come under the Fair Play Policy when the game is finish. On the hand you could have easily stalemated him and ended up in a draw instead.
Stalemate was a theoretical possibility, of course, but a very unlikely one.
His unwillingness to resign even with the offer of a rematch, on its own, would not constitute any sort of abuse or violation of fair play, but taken collectively along with his absurd draw offer, his stalling on each subsequent move, his stated hope that he might still win on time (along with his feigned ignorance -- "Can a player win on time?"), as well as his other insulting and irritating remarks, and then the pièce de résistance, his sudden invoking of the vacation privilege, a very clear picture emerges, wouldn't you say?
I think it's fair to say that chess.com would be seriously remiss not to have a word with this individual.
I wouldn't waste any more of your time, trying to justify yourself to a bunch of people who would, probably do the same thing, knowing they'd do it spitefully, instead of using good etiquette, though they themselves would want to not have someone do to them, as it has been done to you. Its interesting how abundantly from the heart the mouth speaks, how easy it is to see through people,and that they try to manipulate and hide their double standards, all the while expecting you to be the good samaritan. For the record, I would mention every injustice from the roof tops, if that is what it takes to get people to stop. Maybe when they realize no one will play them, they will rethink their behavior.

Anyway, I'm satisfied now that I've called enough attention to the matter, and am ready to let it go. Sorry if anyone thinks this was just a total waste of bandwidth. I suppose, in a sense, you could say I was "psyched" by this person. But hey, I'm only human! :-)
I would say that while you may win the game, it is clear they won the match. He strove to annoy you and you gave him exactly what he wanted.
Well, if he (or anyone else, for that matter) believes it's to his credit that he was successful in annoying me, then all I can say is that they must be living in a very different universe than I do. Not something I would take pride in, that's for sure.
But to each his own, I suppose. Takes all kinds, as they say.

Thank you! Clearly someone who "gets it".
In my many years online, I've encountered more than my fair share of people who seem to make a hobby of disagreeing with others, regardless of the correctness of their position. Experience has taught me that it doesn't take too long to figure out whether you're debating an idea with a reasonable individual, or just wasting your time on someone who simply enjoys playing the devil's advocate.
I suspect that chess.com must have contacted the individual I was talking about very recently, as he's now suddenly back from his "vacation", and his tone and demeanor have take a 180-degree turn. Still hasn't made his move, though. :-)

Who is this idiot? I've played a guy like this before.
I've been hesitant to name names here, as I'm not sure if that would be against some stated chess.com policy, but I would very much like to warn people away from playing with this individual. Check out my "online games" and I'm sure you'll figure it out in a snap. :-)

But would you yourself take pride in allowing someone to affect you this much?
Of course not, not at all. But everyone has their limit, don't you think? I endured about all the nonsense I could stand from this character before finally deciding it was time to do something about it. Believe me, I'd have much preferred not to have had it come to this.
Who was it that said, "All it takes for evil men to triumph is for good men to do nothing."? Seems rather apropos to me.

Would you believe he just sent me yet another draw offer?
Unbelievable!

Such a thing has happened to most of us. I didn`t understand why some people wanted to waste their time and vacation time just to lose a bit later. If you are not a premium meber your opponent can hope you will lose on time. But I got an interesting answer from one of my opponents who did the same - he knew he was gonna be beaten but he was waiting for my rating to increase a bit to lose less points.

...did you accept?
Yeah, right! :-)
No, I simply clicked on the "no draw" button without saying anything to him. He now has 74 minutes left. Cannot wait to be rid of this person!

There are some weird things about that game:
a) Your opponent played a completely pitiful game. That was a pitiful game for an 800 player. Not sure what that was about.
b) He seems to finish lots of other games and doesn't seem to mind losing. The guy has 500+ completed games, many very recently.
c) The game is completely utterly thoroughly over. More over than many other games he has resigned.
What did you do to honk him off so much?
I was thinking the same thing.

I am with the OP on this one. It is bad enough that it happens in 'Lets Play' online games, but I have been in a tournament for the better part of a year. For the last three months, one game, with one staller, has been holding the entire tournament from moving to the next round. Staff doesn't care.
For all of those who say it's just the rules, keep in mind that chess.com writes the vacation rules...it's not part of the game. I either have to put up with the abuse, or play 'no vacation' tourneys exclusively. There are many solutions that allow for vacation time but eradicate the abuse. We are all victims and the best we can do is alert each other so we can block these folks as well.

Just for the record: no, that's not the person I've been talking about. :-)
Your own personal version of this player?

I just can't imagine how a person could derive any satisfaction from using these sorts of ploys. It really speaks volumes about their character and integrity, this eagerness and willingness to try to achieve "victory", however hollow and meaningless it may be.
Sad, really.
