If I was a pool operator and another operator came into my thread and offered this up I would see it as hostile and be apprehensive also. He has his own pool. Even if is stats aren't constantly updated, anyone can calculate the sweet spot with some accuracy and try it out. There is no reason to repeatedly challenge another operator to exploiting their pool at the detriment of their users either way. That was adding fuel to the fire at a time when the whole conversation was going downhill.
slush didn't just walk in there saying "hey ima assault your pool". He defended his score system, that FairUser and Geebus presented as unfair. He exposed how it was mathematically yielding the same result as a share based pool, and how it protected against Raulo's attack. Now you don't see slush saying how he'll attack Tycho's pool to prove share based distribution vulnerable, simply because you don't see Tycho pretending score based systems are unfair.
Now, it is up to one's opinion to disregard mathematical evidence. If you manage to build a successful pool while remaining exposed to an exploit, the more power to you. It is a different matter if such opinion is the basis of one's criticism of the mathematical evidence. In a public discussion, your opinion doesn't weight the same as a mathematical theory.
Ill weigh in here. Most of the above is true however towards the end they did actually accept slush's challenge right before it was locked out. Also much of the confusion in the thread came from members AND non-members adding nothing constructive to the conversation mostly complaining about long rounds even though the pool was doing fine for its hash rate. There was an awful lot of critisim going on, much more than any other pool and im sure that was frustrating for two pool operators who weren't making a mint off running it like Slush
For information I tried the pool with the moded miner. I related that part of the discussion because it led to the locking of the thread. To the question "what are the downsides of BitcoinPool.com", i answered "the pool hopping", which is also relevant to the discussion prior to the lock down. And however frustrating it might have been FU and G, you might consider the fact that they're the ones who accused slush of cheating his pool. You should be prepared for a flame war when you go around flaming others. I mean, this is the internet.
I think this is a perfectly fair and open challenge so long as he doesn't try and hide it from everyone.
Maybe yes, maybe no. I don't speak for slush but i can come up with a few arguments as to why he has little interest in performing that test under all these conditions. I'll elaborate if you so desire. Note also that slush offered to perform the attack under his name before Geebus gave in.
