Two months after she gave birth to twins, Ahna Tessler was feeling confined in her Manhattan apartment and in need of artistic expression. So on Jan. 14 Ms. Tessler, a comedian who lives on the Upper West Side, did what came naturally: she recorded a humorous skit that incorporated her routine of breast-feeding her babies, Madelyn and Elliot, and tried to post the video on the online comedy site Funny or Die.

But a few hours after uploading the video, Ms. Tessler discovered that it had not been published — and that all of her previous Funny or Die videos had been taken down, and her account with the site had been suspended. When she asked Funny or Die for an explanation, she was told “the breast-feeding video” was the cause.

After an inquiry from The New York Times, Funny or Die restored Ms. Tessler’s account and her videos. But the incident was the latest example of how the depiction of nursing bedevils popular Web sites, online communities and other mass media, and left Ms. Tessler uncertain about Funny or Die’s overall standards.

“If I wanted to shock them,” Ms. Tessler said in a telephone interview, “I would have shown my breasts in a very sexual manner. I wouldn’t have been feeding my children.”
