Certain Pokemon GO hunting grounds have been deemed inappropriate, such as the US Holocaust Memorial Museum and the Arlington National Cemetery.
As a result, the locations have asked people to refrain from trying to catch Pokemon while they are visiting.
According to BBC, a spokesperson at the museum said that playing the game inside the memorial "was extremely inappropriate".
Meanwhile the cemetery has also asked visitors to refrain from playing the game on the grounds.
The two spots are apparently also Pokestops, meaning that players can visit them to get virtual items - which will attract even more users to the grounds than any regular Pokemon spot.
It is common for Pokestops to be located at landmarks, with many churches featuring on the app.
However the museum is looking to get their Pokestop removed from the game.
The cemetery also said that "Playing games such as Pokemon Go on these hallowed grounds would not be deemed appropriate."
