Google has marked "Search Engine" site as SPAM. Please help

Hi,

I am not sure if this is right place to ask this question. I request moderators, please move this thread to right place if this is wrong place.

I have developed a site which scraps data from other sites and creates an index in it for search purpose. It is a graphics search engine like freepik.com.
But Google has marked it as pure spam. Google webmaster tools is showing the following error:

Please help.

How would Google know the site can show scraped content? AFAIK Google doesn’t submit search forms at sites but only scrapes what the site pages display.
Do you provide links to the sources like Google does with its scraped content?
