Does cleaning Hoboken graffiti help?

Some places in Hoboken that get “tagged” by graffiti vandals quickly rectify the situation by either removing it or painting over it in order to preserve the quality of the neighborhood.

Other places I’ve noticed, leave them up for longer periods of time – like this area near 3rd & Park. Is it that they don’t have the money to remove it, or don’t bother because it’ll come back again soon enough?
