<snip>or arrange similar shit posts into a separate board and delete later, so as it acts as a reminder to others and to the creator of such post on the kind of post not to make and present?
The thread starter should be aware that their post was deleted, even if they do not get a system message to that effect and that should be a deterrent to making such posts. If they do not notice that a whole thread they created can no longer be accessed they will not notice it getting moved to a separate board or locking it for a while.
If others do not see that type of post anywhere on a board, that should be a pointer not to make similar posts.
The problem of most thread starters that create shit post usually doesn’t revisit their thread once they created it. Most of the time the thread was deleted without being notice or they just notice it when they didn’t qualify for the post quota on signature campaign because the thread was deleted without notification.
I partly agree about temporary lock especially on thread that was deleted on gambling board. Some topic there was deleted even though it’s really a gambling related topic and which is more suitable than sports discussion but in general I agree that shit post should be deleted immediately.
