Where does it state that one can't bump a thread older then 30 days? The only thing I can find is that it is frowned upon to bump reviews older then 30 days UNLESS new relevent information is provided. In fact that rule states threads are allowed to flow on and be timeless, so closing those threads is not needed and a bit of a stretch.
Not only have the local Kansas City mods stated to not bump old threads, you have closed them. Most recent example: http://www.eccie.net/showthread.php?t=125124
This has been happening more and more as of late and its something I strongly disagree with based on the information being relevant.
#13 - In our review forums, be mindful of the 'maturity' of threads you are posting to, ie. the date of the last item posted. We ask that you refrain from posting to a review in which the last post was made 30 or more days ago. Some exceptions may apply if you are providing relevant, valuable or updated information about the provider, but as a general rule of thumb, this can best be accomplished by writing a new review altogether and avoiding the bumping of old ones. This applies to our review forums, in particular, as discussion threads are often allowed to flow for an unspecified length of time.
