What I see is indistinguishable from spam but with more annoying intention (I get into this in detail below) amounting to harassment. I'm surprised that this behavior is tolerated and not identified as a source of unkind communication. It isn't tolerated, but it is also something that those administrating gnu-misc-discuss@ (or any GNU list) can do little about. You've been forcefully subscribed to another list, the GNU project is not in control of it. We cannot filter who sends what to you specifically which is the case here.
