Large hashing power will always be very carefully on selecting pools.
The eligius pool is now a "clean" one with a "potential" tiny black corner, and others 3 big is totally clean like the sky until now.
If you own 1000+T, which one will you choose?
What does Bruce mean by that?
He's trolling.
Basically saying when someone with 1Ph/s is looking for a pool, they will skip Eligius because of his slander.
Too bad for him, Eligius is a no-fee pool, and the pool operator couldn't care less if people go elsewhere...
(or at least that was my attitude when people tried crap like that)
