Can't see why this would be bad for the drama section. No editing applies to prevent people from erasing their stupid post to prevent further taunting. I can't see where this would cause a problem unless someone were to make a dumb post, notice before anyone replied, then make a magical anti-post to cancel out the first in a spectacular burst of energy.
However, the idea as a whole seems like too much work with too little payoff. If someone intentionally posts a gazillion messages in a row as spam they get banned.
Because most of the time that's what's posted.
Shouldn't this go to offtopic, or maybe like, General discussion or something
Nope. As a suggestion, it fits best here.
