EDIT: Check the literal language-setting on your comment editor. I just ran-into this in another thread, and found mine had been changed to:
~~I would copy and re-post. Leave a comment about why on the original, then delete the original post. The admins/mods will still be able to see that, so if they get curious about the re-post, they shouldn't need to contact you in order to figure it out.
Alternately, re-post in another (related) community hosted elsewhere(another instance), then cross-post that to the original community.~~
