I mentioned in a sibling thread that this requirement was originally added out of caution, mainly to discourage spam submissions. It no longer seems necessary, and I was not entirely happy with it either, so I have removed it now. Thanks for the discussion here, which prompted me to drop the restrictive requirement.
