I approved it because it was an Anonymous Monk post and the original poster (assuming that he is not a monk in hiding) would otherwise not see see the original post (or indeed see any replies that may be made) and may be tempted to post again.

In general beating on a limited resource in this fashion is a Bad Thing^TM. Note that any bot in this case is bad because it is keeping a channel locked, but unused, and is therefore denying other users access so that OP can come along, without regard to anyone else, at his leisure and use the limited resource. The pathalogical case comes when all the "users" are bots and no-one actually uses the site. Do you want to encourage that?
