I’ll re-try. I did run through the codepath, and all the assumptions I could find appeared to be valid based upon the values provided in site settings.
EDIT: I was able to repro using copy/paste on a second post with the settings provided above. I will reset them to defaults and see if I can find any correlation.
EDIT 2: I was able to find the issue.
In this block of code, we’re looking only at the user’s post_count. If a user creates a topic first, that’s not counted as a post. Therefore, when a user copy/pastes a reply, it’s counted as their first post, triggering the protection.
