best practices for handling "defensively" purchased .xxx extension

My company purchased the .xxx extension for one of the website domains I manage. Our company is in an industry that is kid focused and we bought that extension specifically to get it off the market to prevent misuse/abuse.  I'm wondering what people are doing out there in these instances... it would be easy enough to just forward that traffic to our main website but it gives me the creeps a bit. Should I let it go to a black hole? What's the prevailing wisdom on this EEers? Thanks!
