JERSEY CITY -- The anti-gentrifiers are out in full force.

An unknown graffiti "artist" spray-painted "GO HOME YUPPIE SCUM!" on the front of the new residential building next door to City Hall in Downtown Jersey City. Dubbed Charles & Co., the seven-story, 99-unit building, courtesy of developers Paul and Eric Silverman, has not opened yet.

The vandalism comes the week a Jersey City woman Devyn Manibo launched an anti-gentrification campaign called JC Take It Back, a social-media crusade that includes slogans Manibo hopes supporters will post on Facebook and Instagram. One of them is "Go home, yuppie scum."

Charles & Co., the Silvermans' 38th Jersey City building, is located at Grove and Montgomery streets. The anti-yuppie graffiti was painted on the Montgomery Street side.

The graffiti was washed off by noon.

Paul Silverman declined to comment. Manibo has denounced the graffiti, saying her effort is to slow gentrification through social action, not vandalism.
