The MTA launched a new campaign against “manspreading’’ on the city’s subways this year.

Maybe it’s had an impact — or maybe cops are just busier with other crimes.

In any case, officers have actually given out 12 percent fewer summonses for the offensive seat-hogging so far this year compared to 2014.

In January, the MTA launched a courtesy campaign that showed oblivious men spreading out their legs during rush hour.

“Dude . . . stop the spread please,” it read. “It’s a space issue.”

Other ads chastised riders for primping, nail-clipping and performing acrobatics for money.

As of Sunday, cops had issued 1,430 violations to people who broke the MTA’s rules by occupying more than one seat and interfering with other passengers’ comfort.

There were 1,625 summonses given out over the same period last year, authorities said.

Riders who obstruct seats — whether by hogging them, lying down or putting their feet up — face a $50 fine from the Transit Adjudication Bureau in downtown Brooklyn.
