Someone can request and command something at the same time. Presumably, the administrators don't want to have to take down posts and police the site, and appreciate it when users don't make their lives more difficult. This makes the "please" seem legitimate to me. I also disagree on characterizing the usage as "passive-aggressive." I would just call it polite. Underscoring your authority with a peremptory tone seems worse to me.
