Here are the key notes I'd take away from this.
Early Bump:
Posting 2 back-to-back posts in one thread before 4 hours.
Creating several threads to bypass the early bump rule.
Repost:
Do not repost a thread that got closed due to a violation. (Illegal trade/Spam/Services/Posting in the wrong forum).
Top 50:
Do not have more than 4 threads up in the top 50 at any time.
In Ladder Slasher Trading Hall only, 3 topics in top 50 is permitted.
Use the "Report Post" button whenever you see an above rule broken.
Use mediators for all possible trades.
