I noticed that period 25th - 27th September you mentioned on the other thread and wondered what had happened. I rather naively thought it was just bad luck but was surprised as I also mine with BTC Guild and although there can be erratic patches, in the time I have been using BTCG, there hasn't been anywhere near that amount of time passed without a block being found. Quite the opposite really, BTCG is very smooth, even for PPLNS
Like some of the other commentators above, it's sometimes hard to take seriously some of the price movements on the CEX order book. Whilst there's no way to tell for sure, it feels that someone is playing both sides of the ledger.
It would be good to hear an explanation from the company, something longer than just a couple of lines of rebuttal. Your analysis really does require addressing by CEX as it's all out there in plain sight and if there is diversion of client hashing for nefarious uses, it's completely distasteful.
Perhaps CEX needs a genuine competitor to 'keep them honest'?
