Briosafreak informed me that Bethesda have updated their forums and also put up some new rules which means all messages will be deleted if they're not active within 30 days, here's the rule:<blockquote>Also, messages will now only remain on the server for 30 days based on activity, except for pinned threads. So if nobody posts in a thread for 30 days, it'll be deleted. Again, we're trying to improve the performance by keeping the size of the database reasonable.</blockquote>Right...
