If you have working code that you're looking to have peer-reviewed for improvement, your post belongs on Code Review, which was established just for that purpose. If that's not what you're asking, then please edit your post to clearly explain the problem you're having with the code you've posted and ask a specific question related to that code. — Ken White 49 secs ago

Evaluate the request and use a reason like too broad, primarily opinion-based, etc. Then you can mention to the OP that it can be posted on Code Review if it is on-topic.

Automation is king. We do code reviews, and they do creep in depending on who signs off on the approvals - I've never been on a team were it's 100% of all reviewers required to merge, so it's usually "2 accepts / no declines". Automating the check will also help flush out the ones that slipped though and are already in the codebase too. — antonyh 42 secs ago
