as far as i know, you canT be ranked down when you deleted your post, your accounts activity or rank will be the same at the time you rank up.correct me if im wrong?  maybe the op is just confuse of his different alt counts or maybe hes not posting consistently and missed the update of rank activity. @op i suggest you to post often on the forum atleat once a day or if you think this is a bug , you can always contact our admin.
