The PM mailbox issue is most likely due to the server restoration. Mods shouldn't have a cap, but it was probably reset to the normal limits during the restore. As for P2P, it doesn't matter if it is legal or not, Doom9 doesn't want that type of activity promoted here. If you read Doom9's news comments or some of his you can see he is not necessarily anti-P2P, he just thinks it could be harmful to the forum.
