Perhaps it would be better if you asked those admins why they are moving those posts? I know of one who has been harassed by Allan for several months because he did not like it that his duplicate posts were deleted, so he reposted, and reposted and reposted. Take a look at the Moore surname archives on rootsweb. He did this on several surname boards. He has cross posted his messages on both surname and maiden name boards, often switching the names so that the dupes wouldn't be found out. This admin has stuck up for Allan in the past, she has gone back and forth with staff for solutions, and moving the posts from the boards seemed to be the best solution.
Take a look at the Tombstone Inscription board, you will see how many dupes from Allan? He's been around long enough to know how to find his posts, how to ask to have them deleted, how to delete them before posting again, but he just keeps posting anyway. I don't know how many times in the last couple of weeks he's posted dupes to my boards because of a new user ID and it's very easy to delete his old post.
Whether or not the messages belong on a surname board or a cemetery board or a tombstone inscription board or a photos board depends on point of view. Staff at this time said publicly that we must leave them on surname boards, but those that have been having problem with Allan have been given special consideration and have been allowed to move those messages, so what you or others think means nothing and trying to cause trouble among administrators is not a good thing.
