I don't know of too many posts that get locked unless you are counting the moved threads? The mods try to keep things organized and move to proper sections at their discretion . . . If you posted about shaker hood questions, I would think it belongs in the body shop area. If someone else had questions about shaker hoods . . . They should or would look in the body shop area.
It is only polite that we put a moved thread so the original poster can find what area it was moved to. Those threads are locked since it is of no benefit for members to post in the moved thread. They are typically deleted after awhile as they do not benefit the site.
