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.
