There is some amazing graffiti out there, some is artistic/art, even if it is illegal. Most is crap. There is likely some that's so good that it's worth keeping.
Still, it can be art, illegal or not.
I saw this myself outside of the building where I work the other day. I took a picture with my phone, but accidentally erased it.
