As company policy, CCI cannot accept the following sites:
・A site which has no information(/link) about its operating company
・A site run by an individual, not a company
・A site which uses a free mail address (e.g. @gmail.com, @yahoo.co.jp) for its contact address (it is considered that there can be a credit risk in doing business with the company )
・A site that does not meet minimum content requirement
etc..
The sites rejected this time are due to one/some of these reasons.
Hope this info helps.
