I run up the prices in less competitive auctions just for fun occasionally, especially if I think someone is getting too good a deal.
You are not fun.
Do you usually pay for the higher price you are offering?
I mean, dick move, but that has nothing to do with sniping. You could do that at any point during the auction and it would have the same effect.
Question: what kind of fun you are referring to here?
Since, from the outside, it surely sounds like you get pleasure by inflicting some form of suffering on others. But that hopefully isn’t considered fun, is it?
