The promotion was ridiculous.
Ambigious rules made the promo very shady in the first place in my opinion and regardless of how you review promo, the pool operator looks like a moron.
Either he
- knew that 10 blocks will never be hit within 3 hours by his pool and tried to trick others to joining his unprofitable round and does not care about miners.
- or he is just dumb and extremely overestimated the effect of the promotion. He said in IRC that he expected 2 TerraHash, what should make everyone roll eyes, also 2 TH/s would only solve 3 blocks on average within 3 hours ;>
(You might argue that it is obvious that he meant 10 blocks of his pool. For me it was not obvious, so I asked and did not get an answer. Also in IRC he did only answer after several personal directed questions, even though the chan was not very active at all.)
Whatever the reason was, either he is stupid or he tricked miners for short term benefit and both characteristics are severely negative for a pool operator. I assume he is the latter what makes it even worse.
Also I have heard from several people that he promised 1x 6990 to the finder of the block, later he declined that.
I gotta say I also dont understand why he still has 40 GH/s in this heavily stuffed round. I got the feeling many many people dont have a clue how it affects proportional payout when joining a round in the late stage, even though the system is very simple.
I personally would avoid such pools. If you stick with those businesses you demand getting robbed in the end. OP did promote a promotion which was not even a promotion at all. That's why everyone should be pissed, stop their miners, cashout and never come back.
I would not be surprised if OP did find some blocks lately and just did not make them public because he has the plan to orphan the pool anyways and is trying to get the best out of it in the end.
