What difference does it make if the guy has his favorite artists listed on his homepage, typed in a word document or written down on a piece of paper? And its easy enough for the guy to just harvest your partners gallery without even adding them to the list. Maybe your partner should just ASK this guy why he has 400 artists on his list but I dont see why that would be anybodys business anyway.

People need to chill out and quit being so damn paranoid.
