Straightforward situation but the help pages don't explain this aspect well, which surprises me. Can someone clarify for me, and perhaps update the Q&A/FAQ pages to help others who might also get confused?
I wrote an answer to (this question). It was deleted by another user. My request here isn't about the merits of the deletion, it's about my understanding of the situation. The Q&A don't really explain this very well, and I'm confused.
The help page (section: "How can I undelete one of my posts?") suggests asking on Meta if deletion was by "Trusted users". Following the link shows the user has 1869 rep compared to 20k needed for "trusted user", not immediately obvious but I found that info. So the answer wasn't deleted by a "Trusted user" or a moderator, perhaps it was deleted by the system... but the Q&A doesn't actually seem to explain how such a deletion happens, or what to do about it. It isn't clear which type of deletion happened, if different methods have different follow-ups.
It looks like one way to appeal it is to ask via a post on "Meta", but it isn't clear which "Meta" that would be, there are many with that name - is it the Meta for that SE or the general Meta? I also have an "Undelete" button and a "Flag" for moderator attention link, but I'm not clear if it's appropriate to use those or if I should ask on whichever Meta site is meant. If I use them how I clarify for other reviewers why I think it's appropriate, or indeed how I comment on such a delete/undelete action for others?
I figure that if I'm confused by these things, I imagine others will be, so could someone, as well as helping me understand these points, also improve the Q&A page to clarify for others as well?
I emphasise that I'm not asking "why was it deleted" or asking for undeletion here, I'm asking for help in understanding the confusing aspects of the delete/undelete system which aren't well explained when I went to read about it.
