I've been wondering what happened to this project. Unfortunately I missed the free download of the Roxanne track so I was hoping to purchase the record one day. I just recently found that the guy behind Rock Against Trafficking (Gary Miller) passed away in May 2022. This blog post mentions the record and hopes it will be released one day, but at this point I'm doubtful it will ever happen.
The website is still there and a banner pops up mentioning the passing of Gary Miller. So I guess the project isn't completely dead.
