About Resell Rights Product Listing Guideline

Dear guys,
I have difficulties to understand the message sent to me by SEOclerks support team despite I have read the forum listing guideline.

However, so far, SEOclerks support team has done a great job in reply.

I received the message of the following:
"We do review any products on a case by case basis but they will rarely be rejected permitting that all content involved is unique. Duplicate content from reseller products will often be rejected regardless of resale rights."

Question:
What did the sentence highlight above really mean?

Did it mean?

• No duplicate sales page?
  
• Write or rewrite the content from the resell rights product sales page before posting into SEOclerks market?
  
• No copy & paste?

Can anyone explain?

Thank you

Note: Have done a search on the forum & "G-search", no one yet sells the product on SEOclerks.
