Blanking the posts of other users from talk pages other than your own Wikipedia space and other discussions aside from removing internal spam vandalism etc is generally considered vandalism An obvious exception is moving posts to a proper place eg protection requests to WPRFPP Removing personal attacks is often considered legitimate and it is considered acceptable to archive an overly long talk page by creating an archive page and moving the text from the main talk page there Note The above rules do not apply to a users own talk page Editors are granted considerable latitude over editing their own userspace pages including talk pages and blanking ones own user talk page is specifically not prohibited A policy of prohibiting users from removing warnings from their own talk pages was considered and rejected on the grounds that it would create more issues than it would solve  Read the rules regarding page blanking before you act  Capeche
