Self-deleted posts and the 3 vote / 60 day rule
When I delete my own Questions / Answers will the reputation changes because of up-votes/down-votes on the Particular Question/Answer be reversed?
Yes*. However, deleted questions still count when the system is looking at how many poor quality questions you may have asked.
/* If the post is more than 60 days old and has a score of 3+ you don't lose the reputation.
