Domain parking and backlinks question

I have just signed up with Sedo to park some domain names that I have had sitting around making GoDaddy money on the parking of them.

I was wondering if sending backlinks to the parked domains violated any TOS with anyone?

I am assuming it is ok to send backlinks, but what will the search engines see? Will these parked domains rank for anything?

Thanks in advance!

you can't send backlinks when the domain is parked. what you can do is you can take the domain off the parking and build backlinks and then park it again this way you get more traffic this is ok with most of the parking companies.
