Can't really see how he can send 5000 hits without you beeing able to see in your stats where they come from ?
I'd propably start there, track the trafic back to hopefully some way of contacting him and if that keeps failing and he really burns a lot of bandwith send it to a tour 'light' without trailers..
Btw. hate when affiliates don't ansver mails when your trying to help them, had one that got his reff code wrong but never replied to my mails and never got them fixed before he eventualy took the links down, propably blaming the site for not converting
