In my case I posted 2 guns for sale in the same FS thread. After 1 of them sold I decided to close the original thread and relist the remaining gun in a new thread of its own. I received a infraction and had my thread closed immediatelly. No biggie, I new the rules just didnt think it would be a problem.
I Guess everyone thinks it's easier to edit the whole ad instead of just creating a new one!
