Ravens PHP Scripts - Stealing Scripts????

I was recently browsing though my Referred links and I came across a few links from other sites that have a modified version of the script I worked so hard to make and share with the nuke community. this person from SKGD has taken it upon himself to take full credit for my hard work. this really makes me upset that people do this ..I don't mind modified version but why cant they just leave the copyright intact. the nuke community is about sharing with each other and helping each other out not taking stuff and changing the copyright so that you take credit for the software/script this is not what we do. everything I have on my site UrbanClubbers.Com still has the copyright information intact and I believe that's how it should be.
