It has been cleaned up and fenced off.
BTW graffiti has been a Roman tradition for several thousand years.
I was in Pompei looking at graffiti in the 'locker room' of a gymnasium near their collesium. The was a line of graffiti stating that "the women of Pompeii swoon for Flavius"
That line of graffiti, once considered vandalism at its time is now an important insight into the life of the common Roman circa 60AD.
A year or two later I was in Athens at the Acropolis looking at Greek graffiti that was 2500 years old and photographing it. A person approached me and asked what I was doing. I explained my interest in the graffiti and that I photographing it as I was not at all fluent in ancient Greek and hope to translate it later. It turns out the woman who was asking me these question studies ancient Greek graffiti and she gave me a special tour of the ruins to see some of the markings. Tons of great stuff about families, loves, dedications and jokes.
