So, touting the world´s best paying pool and a week later
be negotiating the train-wreck of that pool is just an
honest mistake in your opinion ?
Now, come on... I didn't say "honest" mistake.

I just said "mistake". It happens, and then you scramble to try to make it look like you had it under control, or it was out of your control. That's just human. We all do that at work everyday.

So this guy was busy pumping sales of zen hashlets mining the world´s
best paying pool, so terribly busy that he plain forgot that contracts were
expiring ? And the very same day that pool crashed this hashlet
authentication key debacle came up ? Maybe they´ve forgotten altogether
to renegotiate that pool. Maybe there were no negotiations at all anyway.
