Yes but if you would read some more you would see that some additional rules were added in last days by some big pools and also big nodes. And it is a big problem for some services like BitGo...
Why is bitgo having a problem? I heard that some pools had added measures to ignore tranasctions based on a rule intended to identify the "stress test" spam computers. Is bitgo getting caught in that filter? Even if they were, other pools would mine their tx. Is the problem that bitgo isn't paying sufficient fees to be heard in the sea of spam?
