Should I feel bad for not accepting take backs?

When I make a terrible blunder I resign and move on. Usually yell a bit but then I move on. But sometimes people request a take back. I've pretty much stopped accepting them altogether, and lately I've been cussed at a few times, and had people just stop playing, not resign, but waste the remaining 5 minutes. What's up with that? Should I just give in and accept?

You don't have to. They made the blunder, not you.

My personal policy is: In bullet games, never accept takebacks; in other games, accept takebacks if and only if I haven't replied to the move yet.

Disable takebacks (either in all matches, or only rated matches) in your preferences.

#3, exactly!

The reason for awful blunder as you see it may be just a mousslip. That happens to everyone.

# i also experience this quite often, i never give takeback (of course) and then opp just quits moving. Then i am happy that i did not, as my opp is obviously one with a bad character.

I also never request takeback of course, how barefaced. I resign, say 'gg' and request a rematch

I have removed takebacks from my settings. So, unless the player decides to discontinue before starting, all begging - from either side - becomes next to impossible. Few complain.

No one has complained about my takebacks removal. Their tough if they do.

Yes, you must. Our Lord Botvinnik will punish you with constant loses.
