PokeStops seem to be popping up everywhere — but some of those spots are reportedly leading players of the viral app to inappropriate places.

The 9/11 Memorial is one location that is littered with PokeStops, according to the New York Post. Pokemon Go allows players to “travel between the real world and the virtual world,” where they find and catch different Pokémon species. There are also PokéStops at real locations, such as historical landmarks where players can collect items.

Pokemon Go fans have reportedly been specifically led to the memorial's reflecting pools.

“Koffing, a levitating purple monster with a skull and crossbones on its belly, appeared next to the reflecting pool at the memorial Tuesday — right next to the thousands of names of first responders who lost their lives in the Twin Tower bombing,” the Post said.

“It’s disrespectful to the people who lost families. Playing a game is one thing, but they shouldn’t do it here. This is like a sacred place,” a 61-year-old Staten Island laborer who helped clean up Ground Zero told the publication.

There are also three PokeStops at the Holocaust Museum in Washington, D.C.

"Playing the game is not appropriate in the museum, which is a memorial to the victims of Nazism," Andrew Hollinger, the museum's communications director, told The Washington Post. "We are trying to find out if we can get the museum excluded from the game."

The Washington Post observed on Monday afternoon “plenty of people inside the museum who seemed to be distracted from its haunting exhibits as they tried to ‘catch 'em all,’ as the Pokémon slogan goes.”

Speaking to the app's players, the publication said most of them “at least didn't seem to mean any disrespect.”

"It's not like we came here to play," a 37-year-old woman named Angie who refused to giver her full name said. "But gotta catch 'em all."
