@nadiyar There are some obvious signs like PR description pointing out how it was tested.
Sometimes it's a look on the profile. If someone has 100+ contributions per day across many different projects there is no way they could have spend a reasonable amount of time to review, or even understand the issues.
But in many cases it is more subtle. Like an exessive amount of trivial comments. Then it's hard to tell for sure.
