Some people have their whole "GitHub resumes" built off copy-pasted contributions.

1. Open PR

2. Get comments asking for changes, you only have time to fix it a few days later.

3. PR gets closed as fixed by another PR submitted by a frequent contributor.

4. Find said PR is your exact code with a variable name change (approved instantly through lower 'friend' review standards)

5. Look at that user's profile and notice almost every contributions were copy-pasted from other people.
