I'm confused. Your guidlines listed on the link submittal page are:
* Do not submit mirror sites. Mirror sites are sites that contain identical content, but have altogether different URLs.
Only one site was submitted.
* Do not submit URLs that contain only the same or similar content as other sites you may have listed in the directory. Sites with overlapping and repetitive content are not helpful to users of the directory. Multiple submissions of the same or related sites may result in the exclusion and/or deletion of those and all affiliated sites.
There aren't any other really comprehensive sites that allow searching of VOIP providers by area code, and that list reviews all in one place.
* Do not disguise your submission and submit the same URL more than once. Example:
http://www.dmoz.org and
http://www.dmoz.org/index.html.
Only one URL was submitted.
* Do not submit any site with an address that redirects to another address.
The URL submitted does not redirect.
* The Open Directory has a policy against the inclusion of sites with illegal content. Examples of illegal material include child pornography; libel; material that infringes any intellectual property right; and material that specifically advocates, solicits or abets illegal activity (such as fraud or violence).
Nothing illegal here...
* Do not submit sites "under construction." Wait until a site is complete before submitting it. Sites that are incomplete, contain "Under Construction" notices, or contain broken graphics or links aren't good candidates for the directory.
The site is active.
* Submit pornographic sites to the appropriate category under Adult.
Not pornographic.
* Submit non-English sites to the appropriate category under World.
It's in English.
* Don't submit sites consisting largely of affiliate links.
There are some affiliate links, but it is not largely made of affiliate links. There is functionality to allow people to search for providers and leave and read reviews without ever touching an affiliate link. The site has more content in this area than almost all others.
So, given that it does not violate the guidelines, I don't see how this submittal can be considered spam, nor do I have any idea what you mean by previous submittals. My client has assured me this site has not been submitted before with his knowledge.
Please advise.
