FYI, to clarify, the "too bad they can't spell" is because they misspelled "Inspiration" in the pic, not because people mistake Minstrel for another word--just in cast that was your line of thought.
Second, it's a word like any other, "trouble" is in the eye of the beholder, and if people take issue with it they should probably grow up a bit IMO.
"Rake" was going to be my other suggestion, but a lot of people don't know the meaning of that word in this connotation. So, since Minstrel was one of the suggestions in the OP, I went with that one, as did a few others posting in the thread.
Another thought was "Scoundrel", but that has too much of a negative connotation with it. I figure that is also why WotC went away from Thief and used Rogue instead, too much is implied in the name otherwise.
