At least with Chris Redfield, it makes sense why he gets a lot of that kind of artwork since he's a physically fit man in canon and honestly the art you posted was pretty tame. It's more a generic beefcake drawing than hardcore fetish artwork.
I think Chris Redfield in particular gets this treatment since he got super jacked in Resident Evil 5 and there's the whole boulder punching scene in that game.
Anyway, I typed Vito Scaletta and surprisingly the artwork is very tame for a relatively obscure character. Looks like some watercolor made in a high school art class. Not that good but I've seen a lot worse from DeviantArt.
