Actress and activist Mia Farrow is facing backlash for posting the apparent business address of Walter J. Palmer -- the dentist blamed for killing Cecil the Lion in Zimbabwe.

With more than 32,000 Facebook fans and 655,000 Twitter followers, Farrow sent out two messages Wednesday revealing the infamous dentist's hometown and apparent business address.

"#CecilTheLion -Gentle protector of 6 cubs. Loved by many. Killed by Dentist Walter Palmer," Farrow wrote before revealing the man's hometown, which can be found via a simple online search.

"WANTED in Zimbabwe: Walter Palmer...for luring much loved lion #Cecil from park & slaying him," she wrote in another post revealing the address.

Netizens responded with mixed messages, many immediately scolding the actress for putting Palmer in danger.

"You should be ashamed of yourself," writes one Facebook user. "There is a right way and a wrong way to deal with this issue and planting a target on this man's back is NOT the right way!!!"

"Yes, is very irresponsible of you to post his office address," writes another.

Palmer has since expressed regret for having shot the loved lion, saying Tuesday that he thought the act was legal at the time.

"I had no idea that the lion I took down was a known, local favorite, was collared and part of a study until the end of the hunt," Palmer said. "I relied on the expertise of my local professionals to ensure a legal hunt."

"Again, I deeply regret that my pursuit of an activity I love and practice responsibly and legally resulted in the taking of this lion," he concluded.

Farrow's tweets have since been deleted, although a Facebook post linked to one remains on her timeline. She has not commented further on the issue aside from retweeting other posts, including Arnold Schwarzenegger's message about protecting big cats.
