Following on from fejj's comments, if the messages were stored just once, it would be possible to have all marked as spam if one of the multiple deliverees marked it as spam. This could seriously cut down on work.

Anyone interested in the creation of an Idea Bank where people could document their ideas (for inventions, programs, and other things) in order to make them available for development by others as well as document proof of ideas etc. as possible prior art?
If so, please contact me.
