I find the whole thing to be pretty awesome. What are you afraid of? they might stumble upon your private key, or expose a vulnerability in the system?
It is very stupid to measure the success of this "project" by how much keys it generates per second. What actually does matter is how much of the generated keys you can check against existing DB (aka blockchain) per second. Why is that so difficult to understand?
The probability of finding a bag full of dollar bills just walking down the street is much higher than finding privkey of somebody else's address. And no, finding a bag of dollar bills won't be an indicator for vulnerability in the dollar monetary system.
My take on this "project" is that from the very beginning it has very little in common with the initially proclaimed objective.
I'd have to say that becoin is right on this one, finding a vulnerability is not actually LBC's objective. LBC's objective is to "find a collision in which 2 different private keys go to the same wallet" that's it. Will this break bitcoin? No, but it will be a proof of concept that bitcoin is not as secure as most people think it is.
(And yes, advanced mathematics. Seemed like an easier explanation then starting off on a tangent about bloom filters)
