I recently had my 2nd thread locked

6. Latest Breaking News is the only forum with a no dupe rule

"Statement of Purpose
Post the latest news from reputable mainstream news websites and blogs. Important news of national interest only. No analysis or opinion pieces. No duplicates. News stories must have been published within the last 12 hours. Use the published title of the story as the title of the discussion thread."

Locked dupes there (or anywhere) have no impact beyond the locked thread. Hidden posts (either OPs or replies) will count against you. Five or more within 90 days will disable your ability to post. Posts that are alerted for TOS reasons are sent to a jury. If the jury votes to hide, the post is hidden.

In short dupes make work for the main forum hosts. That's all.

If you'd like to be a host...
You are eligible to serve as a Forum Host if you have a 100% chance of serving on a Jury.
This means that you must:
-Have posted more than 2,000 times
-Have 200 or more days of membership
-Have posted more than 20 times in the last 90 days
-Have had zero hidden posts in the last 90 days
-Be a Star Member

For now, no worries, you're fine as frog hair.
