As an aside, the Financial Times (yes, that one) did a great interview a couple of years ago with prolific London graff artist 10FOOT.
The comments were predictably howling with rage and injustice ("he's a criminal!!", says employee of cartel laundry HSBC), but I enjoyed it a lot.

He is indeed incredibly prolific, anyone taking a train around london will recognise 10FOOT.
But he is not an artist, he literally just tags 10Foot in what could be described as looking like it was done with a marker pen.
something like this is very typical: https://ldngraffiti.co.uk/graffiti/writers/flash?pic=152931&...
I enjoy good graffiti, but 10FOOT does not fall into that category.
