Hah, even some aristocratic examples:
"The 5th Duke of Portland is known to have been a hobby tunneler, although he did no digging himself but rather had workmen build his tunnels."
Hobby tunnel manager, perhaps?

Eccentric aristocrats get trapped by the social norms of their classmates. There's even lore around this. For example, people who don't think Shakespeare actually wrote anything[0] also tend to believe it was written by some aristocrat who couldn't reveal they participated in something as vulgar as creative writing.
