Are there any rules against "necroposting"? A mod deleted the very first message I posted on this forum (regarding partial and total derivatives) because he called it a "necropost". I read the rules carefully, and did not see anything like this, so I am wondering if it is standard for mods to delete users' posts and then site a reason that isn't listed among the rules for the deletion. Also, I knew the thread that I replied to was three years old, and I had every intention of replying to it despite this. I firmly believe that the subject of derivatives is timeless. I also tried replying to the warning that this mod gave me, but the mod has ignored my message so far. Is it also standard on these forums for mods to ignore replies as well? Eventually, it seems to me that I will have to follow the guidelines for "Appealing an infraction", but I'd like to get some feedback before I bother with this. I'm still new to this forum, so I'm still gauging how valuable it would be for me to bother pursuing this.
