Lower leaking, make this more of a general forum

I stumbled on this site when I was researching xenforo and was astounded at how many people dedicate their time to distribute free copies of it online (and how enjoyable it is to browse a site as beautiful as this the silvery whites of facebook start to kill my eyes eventually). I must admit that it's no wonder people are here just to leech off of you guys. It's obvious that 90% of people who stumble on this site did it just like me: Google for some software that you have to pay for and add "free" or "download" at the end and boom, here I am, still wanting the software and if it takes 15 posts to get it instead of laying down some ca$h mony, spam is the only option.

For a community like this, you just need some kind of "hook" to separate the people who are actually insterested in this site from those who just come to hit "download" as fast as humanly possible?
