Ask HN: What to do about spammy domain parking

Recently Australia introduced the .au TLD, with first grab for Australian companies with .com.au and a pre registration for when the .au gets released to the general public. I was looking forward to registering my first name to make a portfolio/blog site, so I pre-registered dre.au A month or two later, today, I got refunded my pre registration fee and the domain got snagged. The only way someone could undercut me was if they had a .com.au domain, which they do: So now both dre.com.au and dre.au are taken, and they are both spammy parked pages. I can make an offer for the .com.au but I cannot for the .au (probably due to bug, .au is new and a lot of whois tools fail to check it) I found the registration belongs to some guy in South Sydney, should I just try and write a letter to ask for the domain? Is there anything else I can do about the domain? seeming it looks fairly illegitimate
