The Wyatt Earp of Anti-Spam
Banning and even outright IP blocking are simple to circumvent today. Stealth moderation of spammers has a use - the spammer thinks he is accomplishing his task and therefore you're not in a ban war with him. This times, however many PM spammers you have.Yeah, if the guy is a spammer, he sure isn't going to be satisfied with sending it to just one member. I would just ban the guy. There are more and better members than him just around the corner. I don't see any advantage to collecting his spam when it's easy enough to ban him.
I've worked adult sites. I know the "clientele." There is so much more going on at a site like that, not the least of which is the special security involved so your members feel safe. You leave a guy like that stay on your site and other, better members will leave. It won't matter that you are diverting his PMs, just the fact that he's on site, visible in either forum posts or in the who's online or member list, you will lose members. Bad actors on an adult site need to go away. Period. And if your members find out you can waylay PMs, how would you convince them you would never do that to them? Some just won't believe you.
I think you are just making this too difficult. Kick his ass out. Be free of him.
Again, just my opinion.

But the other side of the pancake you present is just as useful.
This is like alot of mods you see out there - some may want it, most might not.
I think this mod might be alot more simple to accomplish if no PM is sent at all, except to the spammer's "sent items" folder. Of course, with this there should be no 'gotcha' message, only the default dialog you get when sending a PM.
I smell a usergroup for this, with a mod that adds this option in the usergroup manager. Makes this alot more like "Tachy goes to Coventry" except it's for PMs.
