This is how flexpool operates.
They try disparage and discredit other pools to make themselves look like the best pool to use. They have shills all over reddit with 1-2day mining comparisons showing why everyone should switch

Its pretty comical to see but surprising how many new miners fall for it and are actually switching over.
We don't push them to post those they do it themselves.....that being said new miner's aren't the only ones switching over, Ethermine's biggest single customer switched over half his hash too. Its likely what prompted them to raise payout minimums.
Nothing
we've said isn't true.
We've provided the block data off etherscan and you can see that several of the solo mining pool's blocks are filled with low gwei PPLNS pool payouts instead of higher paying ones. Honestly I'm not sure there is a leg to stand on here, ETH transactions are 100% transparent you can see the block filled with 1gwei transactions which pay a lot less than that solo miner would have gotten.
LOL. A classic trumpian smear. It's never him, it's always "people are saying" or "I've been hearing".
