You would think, but not so.

Bitfury still fill blocks with low fee spam from addy 3QQB6AWxaga6wTs6Xwq8FYppgrGinGu15f before higher fee paying real tx's.
See for example https://blockchain.info/block-index/1477998

Addy https://blockchain.info/address/3QQB6AWxaga6wTs6Xwq8FYppgrGinGu15f has sent 140238tx's, all spam, nearly all relayed by Bitfury.

yes i have seen those before but for every one of these low fee spams there are so much more with higher fees.
and bitfury only finds 11% of the blocks nothing more. so that would be practically ineffective because other miners reject them.

But for every one of these low fee tx's (sending nothing exept a fee) included in a Bitfury block, another higher paying fee is not included, meaning fees rise further. 140,000 tx's from 1 addy, sending nothing except low fee, have been included in Bitfury blocks, while "recommended fee" paying tx's (6x higher fee or more) are left in the mempool.

140,000 tx's at 386 bytes equals around 5.5 blocks created by 1 addy, mined by Bitfury, sending 0 btc.
Can't be helping anything.

since you brought this up i went through it and i encountered this:
https://blockchain.info/block-index/1486455 (mined by AntPool)
Ctrl+F the address it contains 252 of these transactions and it seems like bitfury is not the only miner picking these up after all!

p.s. the block was mined during the spam attack while mempool was full (2017-04-15 11:09:19)

You did not "go through it" very far though(?), or you would see that only a tiny fraction have been mined by other pools.
Some Bitfury blocks include around a thousand of these tx's.

p.s. the block i linked was also mined at the peak of mempool backlog.
