I am a reviewer on pullrequest.com and I can assure you I do not work for free. Many of us are Senior or Lead developers with day jobs, who do this as a side gig and to keep our skills sharp.
During my code reviews, which tend to revolve around Angular and Ionic (that's what I signed up for), I have found lots of outdated practices. I can often provide advice on how to make their code better, show them features that are deprecated and how to address them, and generally make their code better.
As another reviewer has pointed out, we can see the entire code base, not just the current diff. We tend to work with the same companies repeatedly and become familiar their project. Some of the engineering teams treat us as part of their team and ask for advice, which is really cool.
Doing code reviews for pullrequest.com has also made me a better reviewer in my day job and has changed the way I approach my coworkers. It's truly been a win-win.
