Just curious, how many percent of questions that get submitted (and re-submitted) get eventually re-opened after the "significant edit" option was added? I've been submitting review requests for a lot of my questions that don't get re-opened.
Your question was closed as a duplicate. In editing it, you invalidated the existing answer to it (made it so the answer no longer answers your edited question), and so your edit was rolled back. At that point, it was reviewed as "Needs details or clarity" since the previous revision was not clear. You then rolled back the rollback (restoring the version that invalidated the existing answer).
@SonictheAnonymousHedgehog Ok, but what exactly do I do now to re-open that question? Flag the answer? Add more details so that the current answer is not invalidated? I know I can't delete the question because it already has an answer!
A similar situation occurred to me once. Just post a new question. As far as moving this to chat, since not enough comments have been posted here, I (or you) can't do so yet; if you feel this should be in chat, flag for a moderator to do so.
@Enderman I could be wrong but I don't think getting a question reopened helps with question bans. You should focus on improving the questions and making them clearer in hopes that that might get you some upvotes (which do help with question bans). If a question is a duplicate, so be it. Editing a question in a way that invalidates existing answers might attract downvotes instead of upvotes, making getting out of the question ban even more difficult.
Also, note that deleted questions contribute to question bans. So, if you have deleted questions, you should find the salvageable ones, improve, and undelete them. You should find your deleted questions (if any) here (only you and SO mods can see them).
@Spevacus @ShadowTheKidWizard Correction: more than 15. I once posted exactly enough messages to bring it to 15 and it was still auto-deleted. The FAQ says "more than 15".
