'tis but a scratch
Was (Player) a good sport?

Depends how strong you are and the game situation. In fast games I have no problem playing down a queen, so long as the game is still interesting- you simply blundered first, but he might blunder second. But there's a point where it becomes completely pointless and boring.
"Never Resign" and "Always Resign" are both bad mottoes. "Always Resign", in particular, seems like a terrible idea.

My say in this is if you are playing classical chess or long rapid games you should resign when you are down in material. It all depends on your position. In the longer games when your find yourself down in decisive material calculate to see if you have any compensation in you position. In blitz and bullet fight on and maybe you'll find a tactic or checkmating pattern. So it all really depends on your position and the type of game you are playing.
In theory couldn't someone say I was a bad sport if I resign a game after losing a rook or queen if I blundered it? I wouldn't want to seem like a quitter.
From a sportsmanship perspective, I would rather play with somebody who resigns after blundering a major piece than with someone who plays on when the result is all but guaranteed.
Now the answer to the question of if you should resign after blundering a major piece is highly dependent on factors like time control, strength of your opponent, how much material compensation you received for the blundered piece, and the position on the board.
The first thing you need to do is to assess the position and determine how much compensation you have for the lost piece and how to use it to your advantage. If you can create complications on the board, you have an opportunity to recover from your mistake.
Basically, don't resign just because you lost material. Resign because you lost material, are unable to develop counterplay, and you feel that you can't salvage a draw.

was playing my club treasurer in a club tournament , otb , he had a much better grade so got less time , in the game I managed to nab his queen , I was waiting for the handshake but his response inspires me still
only a queen , he said and made me have to work hard to secure the win , I loved his attitude , and always try to bear it in mind whenever the odds go against me in the game

Yes, they could. Some people likely will do that in such a situation. Some will when you you win. I imagine that the site's hope is the vast majority of players rating will do so honestly, which will make petty reports not be statistically significant.

If someone makes me play out a win when I'm heavily up and "unable to lose" and they don't stand a chance they get a thumbs down. Been about three today.

It is quite different in chess from another game like risk, where surrendering down a lot is frowned upon as comeback is always a possibilty. Reason being troop cards and multiple players playing in the same game.. Similar to 4 player chess.

Play to the bitter end .... give the other player a chance to blunder and you're back ...esp blitz games at 800/900 level that you're competing at! Plus you're tactics improve ... even if you the odds are stacked against you they stand to you in the long run
Always play on, you have nothing to lose, as opposed to if you resign, no games have been won by resigning, right? For example, I got stalemate yesterday down two queens, a bishop and a pawn
And you're an 1800? lol Were you giving a simul?
no he was playing bullet chess

would you be embarrassed to be the only one wearing clothes in a nudist colony ? worried what the others think of you ?
Hey it was a time scramble, the guy was trying to get three queens
So basically, he focused on what was important when playing a game of chess.

Just some advice: Never resign AUTOMATICALLY after you see that you just made a blunder, or that the opponent surprised you with something that seems crushing that you overlooked. Not online or face-to-face, not blitz, standard time, or postal (daily). Take a slow, deep breath, try to analyze if your game is completely lost, or not as bad as you thought, and try to find a saving tactic. Then if your position really is lost you can resign.
