I can assure you it's not the same AC over and over because AC comments are throttled by IP address.
However, if slashdot dies because of this, it won't be because of Dice. It will be because like the dinosaurs, we couldn't adapt.
Why should we have to adapt to garbage? I don't think anyone would refuse to adapt to a new paint scheme, it's the fact that the new site is fundamentally and functionally broken by design. The fact that dice felt now was a good time to start forcing users to something so broken shows that they have a fundamental misunderstanding of what this place is about. It's not that the beta site is a little buggy, it's that it is completely broken.
At the very least they should have waited until commenting was at functional parity before revealing their hand but now it's too late, they have revealed the direction of things to come and it does not bode well for the future of the slashdot.org domain.
