Thanks for the heads up.
Two replies - the short: thankfully, you've not missed out on $
The long - you haven't missed out $, and here's why

Actually, an 'strack' link isn't bad at all - please see
http://wiki.toomuchmedia.com/index.php/Strack
Essentially, we use strack to switch codes to the correct site (ie, if a FOC code was entered, but you want to be linked to RealExGirlfriends)
By default, strack does
not count as a new hit - but all sales are tracked - you won't have lost anything.
What we can do is tweak the code so it's an strack that counts as a new hit though - which would probably make sense.
