I think a good solution would be to create a community specifically to connect people who don’t want to share their posts and people willing to provide individual help. They could find each other and DM a conversation. Milking a public forum for advice and then vandalizing it by deleting the post is definitely NOT a good solution, and I do not share your sympathy for people who do that. It’s like curtaining off a few back rows of a bus to use all day as an office - although that could have been funny in a Seinfeld episode.
