I'd always figured that was what happened anyway, since the song they did together was taken off of s3rl's social media pages. I'm hopeful that someone here might have more information on the matter than I do.
Long story short, it turned out that he was just a kid trying to scam his way into the spotlight. I was never paid in any way for the track even though he was selling it on iTunes etc. So yeah, instead of me leaving the track up there for him to keep getting revenue off, I took it down. Lesson learnt =P
