Sixties folkie Janis Ian is fighting The Man again — but this time the man is Mark Zuckerberg.

Ian — whose early recordings were censored because of their socially progressive themes — has been banned from Facebook after reposting a cartoon showing an elderly woman with incongruously perky breasts standing naked in front of a mirror with the caption, “Beauty fades, but implants last forever.”

The “At Seventeen” singer was locked out of the site for 24 hours, then posted the image again only to be given the boot again.

Her wife, Patricia Snyder, told Ian’ s 400,000 followers that they believe the ban’s the work of a troll Ian blocked from her page for making racist remarks, who then complained about the cartoon in retaliation.
