It appears to be a bot on Cryptsy that automatically places smallish orders on both the sell and buy sides. If you put up a big buy or sell wall, it will almost always put up an order 1sat in front of it. If you sell or buy into its orders, it moves the orders on the opposite market side closer.
What if we remove all our orders from Cryptsy and switch to Poloniex?
Let Cryptsy play it's games, we won't be buying or selling there.
