Other videos on the account show people urinating on floors of toilets, on toilet paper, and on walls.
The profile picture, shows a cartoon caricature of a man with a creepy smile, with the words “GANG P*SS” in large letters, accompanied by an image of a toilet that has been crossed out with a red X.
Those who are caught urinating in public could be fined under the Public Order Act, or punished for indecent exposure.
Indecent exposure is a sexual offence, and can land those convicted in jail or on the sex offenders register.
Speaking to MyLondon, the account holder of “Gang P*ssers” said: “The toilet seat remains open but for now I’ll take a step back and continue my business on the floor.”
