These restrictions are a great idea. This stops people from mass flaming/whining/spamming. The forums are mainly a place to get some information about a topic or to even review moderator/admin/developer comments that are posted. People who have game related issues can review posts before commenting or they can go ahead and contact the customer support directly.

I like the idea, even though I personally love to post on forums and join in on discussions, but at least we can look forward to a clean forums, which can be moderated in a timely fashion and those abusing the forums are able to be taken care of quickly as Square Enix do have strict rules & policies, which should be applied to other gaming forums to make them a less aggressive place.
