Another woman labelled a shoplifter denied the accusation.
According to the "about" section of the page it claimed it was created to help Rotorua retailers identify shoplifters who had been caught stealing from various Rotorua and Bay of Plenty shops.
The page warned "Don't STEAL if you don't want to be NAMED and SHAMED".
McLeod's Booksellers manager Fraser Newman said while he would support better communication between police and retailers about shoplifters, he wouldn't support such a Facebook page. He said it could attract abuse.
Netsafe chief technical officer Sean Lyons said the page could breach a person's rights to privacy and freedom of speech.
He said anyone who was accused of shoplifting but hadn't actually been convicted would have had their human rights breached.
"It is a fine line."
Mr Lyons said the fact that people's personal Facebook photos were used rather than security footage made it seem like nothing more than a gossip Facebook site.
He said when police released information about wanted members of the public or shops printed security footage of alleged thieves, there was usually strong evidence against them.
