Hello and thanks for reading,

So what i want to know is can i create a website that will automatically make posts, or essentially duplicate them onto my website???

For example.
I create my website.
My website has a script that looks at craigslist, and whenever they have a new post because somebody needs to sell something, it will appear on my website.

Or if the above is not do able, can i
create a search engine on my website.
I search for example "wooden chairs" and i get results from craigslist on that topic. Once somebody clicks the craigslist ad on my site, it will take them to the ad with my referral link.

Can this be done or would i have to repost all the ads on my site manually? Also if it cannot be done automatically, is there a script, or a way to make it easier to do manually?

Thanks for reading and have a good day
