What are you trying to convey with stating "See post 51-70"? Typically, if you need to reply to something, I'd use the quote tool as I've done here. If I need to reference a post on another page for a user to review for a question, I'd copy/paste that link or you could use quote (or multi-quote) as well.
As a user, I'd rather be like "Oh, ok. I'll just click here to see what they're talking about" than go searching through pages to find post #51.
Ultimately, there are holes, as Marc mentioned, and as I've mentioned, there are more user-friendly ways to address previous content.
