I agree @poolwaffle make your pool source code open source on github or such similar open source sites so suspicions such as these can be allayed. you scrypted the re-direct of pool to ghash.io for the 2x promotion before ...
The GHash proxy was a completely unrelated sort of redirect... And the rest of your post is just as dumb.
Publishing source code would do nothing to alleviate suspicions - you can obviously run something different in the production environment vs the code your publish. What it would do is remove some of WafflePool's market advantage that comes from PoolWaffle's custom stratum implementation, profitability switcher, and other code.
Quite frankly, I am really tired of hearing about this redirect shit. Disable it in your miners and move on. Someone found a cool way to abuse a feature in the mining software we all use - it will probably happen again. Patch, compile, and move on.
Wouldnt it be very easy for a pool owner of a multipool to take 5% hashing power of peoples rigs Randomly
Yes... they could. If they were going to, they wouldn't do it by redirecting mining power to another server - that would make almost no sense. The easier way to skim off a pool is simply to not publish some of the blocks you find. The chances of a miner noticing that is a lot less then a miner noticing he is hashing for a different server (I would say, anyway).
But if a multipool skimmed 5% off the top all the time (or any pool for that matter), it is very likely nobody would mine there. 5% is a pretty noticeable thing when you're talking about the tight margins on mining profitability sometimes.
The reason I keep my hash power on WafflePool most of the time, is because WafflePool always published block found stats. And since the very beginning, I was matching my blocks found against the blocks found by my equipment. After over 1000 blocks discovered for this pool, WafflePool reported all of them correctly. Sadly, due to database load, PoolWaffle did remove the individual blocks found stats. This is less relevant for clarity now that we are mining mainly higher diff coins, but I still miss that reporting - it is certainly part of why most of my hashing power is sitting on VertCoin and not WafflePool right now (oh, and because the profitability margin advantage of multipools has dropped significantly in the past weeks ofc).
