Of course in such a case you could just do a search for "Horny Afternoon" to see if he's been using shark's games (presumably without permission), click 'Play Now' on any of them and find: "Developed by hornygamer" Reason enough to remove it imo.
I'm not trying to "cover" site owner, but most of informations who developed what are correct. I was able to find only few mistakes like Horny, but they can be corrected by contacting site owner. Of course other question is, if he publishing games, after getting permission. Still site respect authors more, then many others.
