Since I don't want to be banned from DVDTalk's forum, I thought I would ask the question:

Is posting a free CarFax Report link OK? (not a referral).

If the free CarFax report is something CarFax allows and is available to the general public I think it's fine.

What isn't allowed is people asking other people to run CarFaxes under the other person's account instead of signing up for an account of their own.
