Contact Dan first, maybe they can do something. Not familiar with Dan, but this will be best way to start minimizing the damage.
And be ready to pay penalty for it. It will be a small amout, offer to pay, and apologize.
And if you are worried that domain can be taken from you by force (legal action), then sell domain to yourself in another identity.
I heard 100 offer is very popular in Dan.com. I had a name listed there with nameservers and before I changed I got 100 offer. I changed the nameservers,however, the buyer adds 10 dollars every week or so to the offer lol. The name is 5L with 99% being English word with wellknown meaning.
