This person got zucced for an innocuous GIF - and the zucc was upheld on manual appeal.
Apparently this is "nudity or sexual activity".
The GIF is, of course, completely innocuous:
Mirrored:
The GIF starts off by showing a man in bed playing with a mobile device while a woman is tending to a baby.
Seeing that the baby is settled, the woman turns around to hug the man, making him unable to play his game.
The man, while hugging the woman, agitates the baby who then kicks the woman.
The woman then goes to tend to the baby, and the man pumps his fist and returns to his mobile device.
In Facebook's infinite wisdom, this countas as "nudity or sexual activity".
Go figure.
