Graffiti becoming more abundant?

[“mobile canvas” taken at Park Pl. & West Broadway]

Is it just me, or are in instances of unchecked graffiti on the rise in NYC? I haven’t been able to find any data on the issue, other than statistics showing the petty crime is on the rise.  But just going off of my personal observation, it seems like I’m seeing more of it around. I actually don’t mind the well planned out tags that are aesthetically appealing. But I think that the hasty little chicken scratch throw-ups that I have been seeing more of, are pure garbage.
