Decision can also be made on derived spam score:
[3 points] PR title contains "update readme" or "update README.md" (case insensitive)
[2 points] PR body/description is empty or contains less than 20 characters
[3 points] Only README.md file is modified (single file change)
[2 points] Total additions and deletions are less than 5 lines (trivial changes)
[3 points] GitHub account age is less than 7 days old
[1 point] User has fewer than 2 public repositories on their profile
[2 point] PR has no linked issues or references
[2 points] Commit message is generic (e.g., "update", "fix", "changes", single word)
[1 point] User has zero contributions to other repositories
[2 points] Changes are only whitespace, formatting, or single character typos
Scoring Thresholds
[6-8 points] Label as "potential-spam" for manual review
[9-11 points] Label as "likely-spam" for manual review
[12+ points] Label as "confirmed-spam" and auto-close PR
Note: A separate reusable github action can be created with all this that any repo can use.
