VGMix.com is still registered. Not parked. Not stolen.
At this point, for the domain to be showing up with NOTHING they either deleted everything in the hosting account, or re-pointed it somewhere else, or a number of other things.
We know 2 things:
1) They didn't let the DOMAIN just up and die.
2) They (probably) didn't let the hosting account go unpaid and die.
Essentially this is happening more likely because someone DID something, rather than someone NOT doing something.
VGMix is a domain that, like OCReMix, would be pretty much stolen immediately if it was let go.
So...yea.
