Yep, when it comes to rooting, jailbreaking, or even softmodding a console, there's always a few people willing to try to monetize it.
When it comes to root-android.org, if they're the kinda service that makes you pay to download the rooting tools and give next to no support (haven't checked their site), then it sounds similar to the situation the Wii/homebrew channel guys had to deal with a few years back.
Some rather unscrupulous people had taken their tools, rebranded the install package, then started selling it to those who didn't know any better. It got to the point where the HomeBrew Channel guys (Team Twizzers) re-wrote their install package to include a "Scam Screen" before the main installer started, informing people that "if you paid anyone for this software, you got scammed." That seriously put a thorn in some of the scammers sides, as they could no longer sell the newer versions of the HomeBrew channel software.
Perhaps our rooting devs should consider similar approaches?
