I personally can't speak to this as DK isn't legal where I reside as of yet, but it will soon.
One thing I would do is make sure to check their rules and make sure they can't come back to you and say sorry, you broke rule ABC. If you're good to go with no rules being broken, I can't see why you wouldn't continue doing what you're doing.
If you have a healthy enough balance, time to step it up in these situations and maximize your profit potential.
