NAPLES, Fla. - An alarming social media trend that's had the nation on high alert has made its way to southwest Florida.

Online "purges" are based on the summer blockbuster sequel, "The Purge: Anarchy," in which all crime is legal for 12 hours.  Social media users have brought the fictional premise into the realm of reality by encouraging each other to "purge" nude photos of people.

The Collier County Sheriff's Office is investigating four cases in southwest Florida. Deputies hope to spread the word to local parents.

Laverne Miller of Naples, who has a 14-year-old daughter, told WINK News she didn't know about the "purges," but now that she is aware, she will monitor her daughter's online activity more closely.

"I think it's very scary," Miller said. "I think more people, including myself, need to take more action as far as contacting those that are responsible."

With the anonymity enjoyed by internet users, pinpointing those responsible might not be easy, but other social media users are taking action.

Anti-purge and satirical tweets and Facebook pages are popping up.

Since many users reported the "Official Purge" Facebook page, Facebook deleted the account.

CCSO is urging parents to talk to teens about responsible online behavior.

If you have any information that can help lead investigators to the so-called "purgers," call CCSO at 239-252-9300, or Crime Stoppers at 1-800-780-8477.
