This post will probably be deleted by moderators, but I'm curious how many people welcome a moderator changing their posts under whatever pretext.
Moderation is a job of moderator, which is not related to editing posts in most of cases. If a post is zero value, they will simply delete it. Usually, moderator only edits a post if it's a merge of some continuous posts, with a note on reason of post merging.
2. Let Mods edit out the outdated information?
Mods are not supposed to edit the
content of a post, even if it's a sticky. Mod edits should be limited to non-content things like fixing broken bbcode, merging posts, etc., so that nobody ever has reason to complain that a mod "put words in their mouth". Even if a post is violating the rules, and editing out a word/sentence/paragraph would make it no longer in violation of the rules, this kind of content-edit should not be done; the post should just be deleted.
