There is a post I want either deleted or to go into EC's archives so no one sees it. But since I can't delete it myself, I think it's better to just let it go into EC's archived posts. I've gotten a lot of negative feedback on the post, and I got some advice out of it, although one of the posters is very rude. What are my options?
I think EC tends to not delete posts if they can avoid it. I can't help you, but I think you'll have a better chance of finding helpful answers/mod action on the Help & Feedback forum.
Unless you haven't already, you can ask staff to delete it. There's no guarantee it would be deleted, depending on what it is and why and if it's gotten lots of responses, etc. but only they can tell you for sure, since they're the only ones who have the forum permissions to do so.
