Apparently there is a version of post deletion where it can still be seen from the user profile, like the last Will Newsome's post, but it is no longer indexed by search engines. This is just a conjecture, though. I have never deleted my own posts, so I have no experience with that.
Previous thread
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one.
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
