I had a good chuckle going from Banksy on one line to whether the person is committing a crime on the other - that it's a crime was key to how the article claimed to find Banksy's identity and mentioned as one of the likely factors in why Banksy chose to be anonymous early on :D.
I get you mean whether they are causing any actual harm though (and agree for many such unmaskings), it was just an amusing juxtaposition of literal statements.
