i found that im getting paid accurately for the found blocks, dead on the numbers in fact. about half as much twice as often at Antpool minus the 30% fees which they just keep.
This was a good enough deal for antpoolers when bitcoin was less of a thing and tx fees were insignificant, with Eligius pool drying up a lot of us went to Ant for the zero pool fee.
Antpool has not addressed the point, now that tx fees are running 25-33% and up (of the block reward), They are simply relying on consumer ignorance (a faithful old freind of the merchant throughout history) to dodge/skirt the issue.
They most certainly do address it. It's right on their website:
Assign to you alter Antpool found a new block and the new block confirmations more than 3 (Transaction fees not paid out to miners for maintaining cost and the bonus for our engineers). Earnings = 12.5 BTC * Your share count in 2.5 difficulty cycle / Total share count in 2.5 difficulty cycle
(I put the bold in there so it's clear).
They have ALWAYS kept your fees.
