Am I not supposed to delete wall posts?

Question

I got a post on my wall that told me not to delete wall posts.It had no username.So,why should I not delete my wall posts? Is it for security reason?

Thank you in advance!

It has no username because the person who posted it hit enter a ton of times making a huge blank space. If you scroll down the page you'll see him congratulate you on 2,000 points, and you'll see who posted it.
Posts that put that many spaces can be treated like spam, so if you don't like it then delete it. Don't listen to them.

Don't worry about it, you can delete wall posts on your own wall or posts you've posted on another's wall.

I'm not sure why It's a secret! told you not to delete wall posts on your wall, but nevertheless you can delete wall posts on your own wall.

Honestly I wouldn't listen to anyone who isn't an Expert, Editor or Moderator, or Pokemaster.
