I have to say that as a rule these canned hunts in South Africa were mostly for Lion, although other species were involved. It was bought to the general publics attention by a journalits whos name escapes me for the moment, but he was an english guy.
Similar events have happened with Leopard, including placing Leopards that have been shot cattle raiding and then frozen in deep freeze, only for the client to shoot it out of the tree. Believe me this HAS happened.
Having hunted Africa a few times and conducted trips out there I have built up a good many professional contacts, and get to hear about these stories quite a bit. BUT this was mostly back in the late 1980's early 1990's, and as I have siad before PHASA have nailed most of these bastards into the floor and it is rare that you hear of these events now.
The estate in question was I believe advertsing Wild Boar hunts last year, they have a new manager I believe, this comes from a very reliable source of mine

my advice keep well clear.
