So if you look at this user's current two answers, you'll see links posted back to the site in her profile (which I can safely assume is a for-profit motivation).
I find it a little lame because a large portion of fitness-experienced people probably have connections to some financial interest and are not peddling it on here via their answers.
- Can I start linking to personal trainer's websites I know that I get a kickback from?
- Can I start linking to supplement products that I'm financially vested in?
I'd much rather have a super high wall between commercial interests and the content on here. Related q/a here.
