Yes,
place a sell for 25 BTC
you sell
25BTC plus (1.3%) = 25.01300 sold.
you place a buy for 25 BTC
you buy
25BTC minus (1.3%) = 24.98700 bought.
had this happening all over my logbook during the weekend.
That isn't even 1.3%. What are you smoking? 1.3% of 25 is .325, not .013. If you are going to troll something random, at least get the math right. Looks like you were only being charged .052%, awesome. That's 12.5 times less then you are supposed to be. Not to mention when you sell, the .65% is taken out of your new USD, not added to the bitcoins you sell. I'm going to go out on a limb and say you've never sold on mt gox.
