I just started using LinkVault and was wondering if anyone else had any experience with their text ad network? I know there is a lot of controvery over the benefit and/or liability of your SEO and Google PR with things such as this, but I was looking to get any feedback from anyone who has been using this service for a while.
Their actual domain is link-vault.com, if that helps at all. They are a fairly new company but their infrastructure and network seems fairly robust. I have yet to see what kind of response I get from participating in their network, but I will be sure to post a followup after I have been with them for a while.
