In one answer, a moderator suggested me to improve and re-open my deleted posts. I found one of my posts was deleted due to cross-site duplicate. Due to mistakenly cross site posting, I got some negative score before the post was deleted by me. Is there any way to make it improve and request for re-open. I am affright it is not reopenable because cross site has already an answer with others contribution?
Note that I have gone through the help center post but did not find anything specific about how to deal with deleted posts for cross-site duplicate issues to get rid of the negative scores. Any further knowledge or link will be helpful.
