Actually, if you still remember, your room was ultimately locked by Train lol, I can't even see the locked room now due to that reason. (It was probably set to Administrators-viewable only lol) But yeah, Anzo did gave the order for locking them. However, he also said it's ok to unlock it as long as the spamming is in control. (Well it can't be unlocked either ways now) As for other rooms, no idea, those are not in my memoeries.
DONDABA DENDEN EGAEGAON.
