I would not use this because:

-I can't have my company's source code existing in yet another system. It's already in github and after CircleCI's security failure my desire to have another entry point to source code is very low.

-More importantly: I, and most experienced developers, don't use code review to find simple syntax errors or fix stylistic issues. Code review is a way to socialize your changes and make sure they make sense in the larger system. The code reviewers on a site like this will not understand the larger system with enough to detail to find issues that are not simple syntax errors.

Just my .02
