I remember the old Bungie.net auto locked threads after two weeks of inactivity. I find it humorous that people complained about newcomers not using the search feature when I first stared using the forums. Now that people use the search feature people now
complain about necro posting.
The real problem is search engines have better caches of older threads. That's why it happens a large part of the time. It's something that has been noted. People who do it intentionally arise from time to time but we can handle them quickly if they're
reported. Or if we're just browsing.
