Why there is this much deletion?

Question

Today accidentally I noticed that the number of my answers shown in my user page is far less than it was!

And the worse is that I cannot understand what were them and why they were deleted. There's no choice to see the list of my deleted posts.

After spending a lot of time to find my deleted posts, I could just find one of them, which was deleted in spite of having 2 up votes.

I think everyone will admit that deleting one's post without any notification is not fair at all.

Now I want to know that:

1. Based on which policy there has been this much deletion recently?
2. And why there should be this much privilege for an individual moderator to delete users' posts without any notification and no chance for the user to at least vote her post to be undeleted?

Thanks.

Answer 1

Recently, I have been deleting a large number of posts (the details can be found in my answer on the recent meta post "Please vote based on quality"). Presumably the ones you're asking about were involved in this purge, but I can't explain why any particular post was deleted unless you can point me to an actual deleted answer, as they were deleted for a variety of reasons. Upvotes, especially in the wake of the current situation, are wholly irrelevant.

Due to the very nature of site-moderation, user posts may end up closed and/or deleted with absolutely no notification. Because of how difficult it is for me to leave comments in general, and how often said comments are just taken as something to either be argued with or ignored entirely, I have chosen to forego notifications — especially notifications to established users who should already know by now how the site works — unless I feel them to actually be constructive.

For the most part, I chose not to leave comments because it would only be duplicating information already found in our help centre. Posts which are, among other reasons, very low quality or which don't fundamentally answer the question asked don't belong on the site.

The fact that a regular user cannot cast an undelete vote on a moderator-deleted post is by design, see also the related meta question "Why deleted answers can not be voted for undelete any more?".
