When we introduced the new pause system and the changes to character limits, we were slightly concerned about someone trying stuff like this, but we thought we'd give it some time and see if anyone actually did.
I'd say the best course right now would be to send him an OOC message asking why he feels the need to do this, and warn him that he's skating very close to abuse of the pause system.
If he keeps doing it after that without a very good reason, then we will need to consider stronger measures.
