.edu backlinks for an adult website

Hello
I've got a question for you guys: would it be a good idea to have back-links on a .edu site for your adult website? I know .edu is really valuable but it's not natural for a .edu to link to an adult website. (they are forums so you can just paste them in with your account and normally no one will see them.)
thanks for the answers in advance

Short answer YES.

But if its a site with so many outbound links, i wouldn't recommend using them because it will be useless
