Whatever it is seems to be continuing... Another 1143drk went through 18:00. Can't figure out whether it's automated or not...
Maybe it's two individuals who wish to exchange DRK for goods/services and are using it as a kind of escrow service? I can't think of a rational explanation other than that!

Might just be some botter put the decimal point in the wrong place before launching them. Hope they aren't house bots, and the owner wakes up to a shitload of fees.

Ha, true. Hopefully it is just a fat finger!

Either way it's not affecting the price so it'll be interesting to see how long it goes on for...
Edit: wish I had some coin on Cryptsy just so i could try buy/sell into it and disrupt the trade...!
