> Some courts such as the District Court for the District of Massachusetts have explicitly stated that "fee exempt PACER users must refrain from the use of RECAP,"[13]
I'm not sure if this is binding, or applies to fee-paying users.
Generalia specialibus non derogant so yeah, the warning was specifically for fee-exempt (like if a judge gives you research waiver from the $.10 fee because you're indigent, pro se etc.) users.
