Yeah, it's a fine line. We do get lots of traffic, which is absolutely amazing. I just prefer that people use the latest version, get it from the real source, and have as positive of an experience as possible. I also require people's emails for downloads on this site which really helps to boost sales, to be completely honest. It's helped me turn it into a legitimate project instead of just a hobby thing.
That said, I'm not about to go and play download police and raise a stink; I do recognize the value of additional exposure. However, if an external download link ever got more popular (higher up in search results) than the official LaunchBox download page, we'd have a problem because I'd lose a lot of my current marketing opportunities.
I really hate mass email and spam, so I was very hesitant to ever send any mass email, but honestly I've gotten very positive responses from it. Most people seem happy to receive legitimate valuable content related to LaunchBox via email, so that's been extremely valuable and I'd hate to lose that opportunity.
