A Twitter use who takes pictures of parking placards used by off-duty police and other drivers in order to shirk parking laws says that he got a threatening visit from members of the Internal Affairs Bureau, with the message to stop tweeting.

The Post spoke to one of the anonymous people who runs @placardabuse about the police encounter. The Twitter account is dedicated to sharing pictures of drivers who don't get ticketed because they put parking placards, NYPD vests or other items that are supposed to get them "professional courtesy" in their car windshield, whether the parking is legal or not. The contributor told the Post that cops visited him at his home in February when he was putting his kid to bed.

"It was hostile from the beginning," the Twitter vigilante told the paper. "The questions seemed geared toward why I was making a complaint and why I was trying to get the officer jammed up."

@placardabuse is run by a group of people, according to in an interview with the Tribeca Citizen earlier this year. In the interview, one of the people who runs the account told the website that "some of our contributors have encountered harassment by the police, ranging from late-night phone calls, having their photos posted on the internet with menacing comments, and even a nighttime visit from the Internal Affairs Bureau."

The person who spoke to the Tribeca Citizen also said that the mission of the account stems from the fact that "a system where some people have to play by the rules and others do not is unfair and cannot be tolerated. This is a tale of two cities: those who abide by the law and those who get over on us."

Nice sidewalk parking at @NYPD1Pct yesterday.



But @JPeterDonald want us to believe @NYPDPatrolServ is providing real enforcement... pic.twitter.com/xq1TPL4LJ2 — placard corruption (@placardabuse) June 24, 2017

The issue of abuse of city-issued parking placards got a dose of attention earlier this year, after Mayor de Blasio agreed to give thousands of parking placards to teachers, while also promising to enforce their proper use. As we reported at the time, city placards allow driver to "park at meters without charge, and in "No Parking" spaces, as well as truck loading zones, in most cases. Placards do not authorize parking in front of fire hydrants, in bus stops or taxi loading zones, in front of driveways, or double parking generally."

Wait, we're confused... does the vest transform this Acura into a truck or something? How's that work @NYPDTransit? Maybe @NYCMayor knows? pic.twitter.com/F5MREjgGRX — placard corruption (@placardabuse) June 24, 2017

An NYPD spokesperson told the Post that it was impossible to verify if the visit happened without the name of the person who made it.
