That is a bunch of traffic.
If you have a CJ account, or any other affiliate account, you could surely convert some of that into income.
You wouldn't even need to fill up your own page with ads, you could just redirect directly to an advertiser's landing page, taking the load off your account.
If you wanted, you could probably even sell that traffic to someone that has something relevant to what they're looking for. Then just changing that 403 to a 301 could just send it all their way.
Also, I'm not familiar with what you had, or about what would be auto-updating, but is it something where you can tell which requests are from people and which aren't? Maybe by user agent? Specific file name request?
I guess HTTP_REFERER could be a tip off to a certain extent, but it would be nice to be able to drill it down more.
Maybe even a blank user-agent, or something similar that is rare with browsers.
If so, then I'd expand the .htaccess rules to continue 403'ing anything that's not a human, but send humans to where you want them. That way, you can still make money from people while blocking bots, programs, etc...
You could even poke around the affiliate forums at places like Digital Point for more ideas.
If you end up making too much money from the traffic and can't figure out how to spend all of it, I wouldn't mind having a new Mercedes SL65 AMG. It's only around $180,000 though, so if that's not enough spending, I'll take a few of them.
