For background, see here and here.
In short, under the "executive privilege undelete rule", the OP is allowed to undelete their own post using a single vote, if some combination of upvotes and answers is present on the question.
I am in favor of this rule. It is a sensible protection; if a question has proven itself to be a popular question, this rule serves as a safety valve against it being bludgeoned to death by the Exclusionists.
However, this question (Revision History)(deleted, requires 10K rep to view) turned into a tennis match, as three users and the OP repeatedly deleted and undeleted the question.
To avoid this problem, I propose the following changes. I know that not everyone will agree with some or all of these changes; I just wanted to offer them up here for discussion.
Here are the proposed changes:
Under the executive privilege rule described above, the OP is allowed to undelete their own post using their single vote once, but only once. If the community still thinks it should be deleted, it should stay deleted.
Users may cast a delete vote only once on the same question. This is already how close votes work. It makes no sense to have an executive privilege undelete, only for it to be cancelled by the same delete votes from the same users.
Community Wiki posts do not get executive undelete privileges, since the post is owned by the community.
