In an answer for Deleted Question: Impact to Reputation, it's quoted that reputation earned from posts

  1. with score ≥ 3
  2. "visible on the site for ≥ 60 days"

would be retained despite their deletion.

I clicked on the linked FAQ and the following text puzzled me.

Are there exceptions?

Occasionally some exceptions are made. Often, these exceptions come in to play when:

  • All answers are more than 60 days old, and have 3, or higher score (the standard prevention against deleting answered questions is there so answerers don't lose rep, but if all answers have been visible for at least 60 days and have a score of +3 or higher, this is a moot point since their rep will be kept)

To concisely write my questions, I refer

  • "post with ≥ 60 days old" as "aged post"; and
  • "post with score ≥ 3" as "highly-voted post".

As a participant of Math.SE, I come up naturally with the following questions.

  1. What is the scope of these two criteria? For any type of posts or for answers only?
  2. Can somebody help me to understand "All answers are more than 60 days old"? I find two ways in reading this.
    • "when all answers [to the deleted question] are more than 60 days old": that seems bizarre since a highly-voted, aged question might attract new answers with score < 3.
    • "when all [deleted] answers [which] are more than 60 days old": this seems more sensible, but what about deleted, aged, highly-voted questions?
  3. "visible on the site for ≥ 60 days" is different from "60 days old". Which one is correct?
    • The later means the time elapsed after post creation.
    • The former is duration of deletion substracted from the later.
  4. In the quoted answer, it's written "> 60 days" outside the bracket, and "≥ 60 days" inside the bracket. Which one is correct?
  5. How is the number of days for which a post is visible calculated in case of multiple un-/deletion cycles? Here're two possible ways:
    • We calculate duration between an undeletion and a deletion in (milli)seconds and add them up before rounding them (up/down/off?) to an integer; or
    • We calculate each duration, and round it (up/down/off?) to an integer before adding them up.

Thanks for reading.

It's actually very simple: you get to keep the reputation if the post

  • has a score of 3 or higher
  • is deleted 60 days (1440 hours, 86400 minutes) later than its creation timestamp.

It doesn't matter whether it's an answer or a question, how long it actually has been visible, or even how long it was on the site: I recently permanently earned 70 reputation on Literature Stack Exchange because a Meta Stack Exchange post of mine scoring 7 that was more than 60 days old was migrated there by accident and reversed two minutes later.

  • In case anyone's wondering how a post was migrated despite it being more than 60 days old: staff can bypass the restriction. I've so far not gotten a clear answer as to whether the system simply allows use of the normal tool by staff, or if some special dev route is required. Commented Feb 22, 2022 at 20:45
