Is there something I'm missing?

I’m continually stupified at the number of people that manage to do the following:

1. Look at the front page of audiodamage.com where every short product description says something to the effect of “US$39.00 for AU and VST.”

2. Look at each and every product page, under the heading “Download includes all platforms listed below,” where the iconography for Windows VST and OS X VST and AU are shown, right next to the text that explains what they mean.

3. Make a purchase, and after doing so, log in to their account and click the link that says either “AU/VST OSX” or “VST WIN,” open the resulting file, and install it.

4. Write me and say “I’ve tried restarting ProTools several times, and the plugin I bought doesn’t show up. What am I doing wrong?”

Oh, where to start. Let me just say this: it’s a good thing leaded gas isn’t available any more, because there’d be a lot of home studio users with fucked up catalytic convertors in their cars. That aside, is anyone in possession of an idea as to how I might dissuade ProTools users any further than I already do? (Noting item #10 in the first section of the AD FAQ and item #7 in the third section, which nobody apparently reads.) I’d rather not put a banner on the top of the front page that says “RTAS USERS TURN BACK NOW” or something, but quite frankly, I’m at a loss as to how to save these people from themselves.

And the first person that writes “well, you could just make RTAS products” obviously doesn’t know how happy I am to ban people that don’t pay attention.
