This scares the hell out of me, anyone know these guys/want to warn them?

this just saves the hastle of using a chainwhip
a lockring would/should still be used

Many track riders don't use lockrings. At the world cup level, you see very few lockrings.
But my bigger question is ... so you'd sacrifice the paint on your bottom bracket to snag the chain hard enough to do this maneuver? Plus you'd be putting some shear force on overlapping chain links that can cause a side plate to pop loose. Huh?

my campy track hub doesn't have a provision for a lockring and it hasn't been a problem on the track for over 10 years

Lockring?
I keep one in my bag in case someone requires them, but I've never used one and don't carry a wrench for it.
The track adapter for my trispoke doesn't even have provision for a lockring.

well, a track adapter having a lockring provision would be a little silly, considering you would just spin off the adapter with the cog/lockring on it, with sufficient backpressure.

It could have been designed so that both lock, but it's not.
I know at least a couple people who have torn threads off pedaling forward in standing starts. I don't think I've even heard any stories of people unthreading a cog while riding the track.

I havent used a loc-ring once on a track. While out on the roads or city obviously its a smart idea. Alot of people dont bother at FCV either.
The biggest risk you run with the locring is your a dummy and dont tighten the cog enough before installing the locring. Without it the cog spins and you have to play catch up to secure it. (It shouldnt come loose in the first place!) with the locring on the cog spins hits the ring and strips the threads. On 2 of the rentals and a riders personal bike Ive seen this happen.

Oh man, don't get me started...
I first learned the craft of bike racing back in the early 70's on the 250m China Creek track in Vancouver, Canada. My first coach was an ex-professional 6-day rider, and one of the first things he taught us was to throw away the lock ring. As long as the cog is tightened properly (using the cog tool and not just finger tight and hoping that pedaling will tighten it - it won't), it will not come loose. He also taught us never to backpedal, another factor in cogs never coming loose, and causing us to become quite smooth riders, adjusting speed and getting out of "situations" simply by steering.
Over 30 years of track experience since has taught me that lockrings are not only useless, they can be dangerous. Suppose the chain comes off the chainring and jams. Without a lock ring, the cog will unthread and the bike will coast, and someone can easily catch the rider when he loses enough speed. With a lock ring, the rear wheel locks up, the bike starts fishtailing, and the rider usually crashes. They're probably even more dangerous on the road. Fixed-gear road bikes usually have brakes, so a cog unthreading is no problem. And as long as the chainring and cog are perfectly lined up, there has to be an awful lot of slack in the chain before it falls off.
It really amuses me to see people lining up to buy lock rings on eBay, and for ridiculous prices.

If only that were the case.
The kids these days, they don't like the handbrakes.
