Well, I happened to be a bit drunk and on the mobile site, so I did just input the numbers and scroll down to the confirm button
This was a way to potentially take a few satoshis for yourself without anyone realizing.
There we agree, and I am kind of flattered you consider me that smart.
If someone stole $3 from you, would you be fine with letting them go without consequences?
Of course I'd be angry about it, I do currently have some user owing me 0.05
BTC since last year, but nothing I can actually do there.
If you don't want to be involved with the funds, then send the whole amount back (minus tx fees) instead of keeping $3 for yourself. You're making yourself involved with the funds by taking 20k satoshis. I agree that it is a small amount, but I personally don't believe that people should be allowed to steal small amounts without consequences.
Right was I was going to propose, to see if you and direwolf would agree that's something reasonable. I believe it is, and I have admitted my mistake (and I think I won't joke around anymore to prevent getting another hot potato like this one)
