I was wondering, because now that I have more than 10k rep, I am able to see deleted questions and answers, which shows that even if you a post, it is not really gone, just invisible for most and you can't really interact with it.
And I can see that this is a good thing in most cases, for instance if somebody was bullying someone else, and trying to mask it through deleting posts, they would probably be spotted by a moderator or a 10k+ user.
However there are some more special extreme times when this may not be a good thing, so for instance if someone found out where another user lived and then posted their personal information such as their address, if that post was then deleted, moderators and users 10k+ would still be able to see it which wouldn't be a good thing because even if all of those users are trustworthy, it's still not a very nice thing, and also accounts get hacked, and computers get hacked so the information wouldn't necessarily be very safe just hidden on the site.
So, for probably rare, but possible extreme cases, can moderators delete posts permanently so that they are not just hidden, but nobody can actually see them? And they can never be undeleted. I understand that there is such a feature for moderators in chat where they can purge the message history as well as delete the message in extreme circumstances, so is there a similar feature for the main site?
And if there is not, then there should be.
