Many forums have/had policies about not doing cross posting (in different categories). I find this similar.

Yes, maybe from the "plagiarism" angle is not very relevant, but I would prefer not to have a system in which people try to "flood" repositories (journals, etc) with the same thing over and over. People looking for new information, people reviewing will get most of the burden to "keep things clean" while for the poster that is not a problem.
