Sounds like you're running a trading bot and are angry because you're encountering weird bugs. Guess what, normal users might not be affected enough for it to matter, certainly not as much as you're trying argue. Let's take my case for example: I've executed 1317 transactions on Bitstamp, totaling $1276.26 in fees. If Bitstamp really added an extra 0.01 to all those transactions, they've stolen $13.17. That's 1% of the fees I've paid. I can see this being a problem, if you are a spammer of 0.01 BTC trades.

BTW, who is the 'spammy fuck' now?

EDIT: I can see the rounding problem in my fees easily, it just doesn't add up to very much in the end. Only ~20 of my 1317 transactions were smaller than 2 dollars.
