No, the trouble is that move only "soft deletes" the message and it'll turn out the way Tufty put it: there is a "trace" showing what was recently there. I had the same problem when I was on staff and would do some trial posts at a staff-only Forum to prepare what would come out in the Hall of Fame (because fixing anything once you'd posted the real thing in HF could be tricky). Those "pre-posts" and try-out posts were meant to be scrapped afterwards, but I could only soft delete them, had to ask cariad to do the permanent deletion.
