Unfortunately, the latest crop of bots are being used to skew the order books by automatically creating orders that have no intention of being filled.  This frustrates traders who are trying to find the real price of a coin.

To combat this, we are making the following changes.

Order Entry
1.Number open orders per market will be limited to 10.
2.Only 100 orders may be placed in a one hour period on a given market.
3.These caps apply both to UI and API trades

This is from bittrex about squashing bots so I don't think they like bots lol  they wouldn't be doing this if bots were making them lots of btc lol
