I don't think so, the idea of a timed ban is to deal out the appropriate amount of punishment, so why would we do so further? Jail is often used to temporarily detain users, for example, if they are bugged/glitched in some way and need to be put out the way, Jail is not often used as a punishment because it allows them to still chat to others, and often continue what they were doing, if the problem is harassment related.
