I wanted to test out some code for mixing RSS feeds and automations, so I decided to build a little news aggregator site. For inspiration I found this site: https://themorningnews.org that just has a single column of headlines, some content/images, and links out to the source site (theres also a somewhat hidden landing page for each individual article).
For my project I did something similar. I pulled data from RSS feeds (NOT necessarily RSS feeds hosted by the source sites themselves), then used data from there to scrape a little bit more data from each source site (only metadata), I also stored the images from each article on my own server to reduce load from hotlinking to their images. I combined all that to create a site similar to the one mentioned above: https://theheadliner.org.
Now that it's done. I'm wondering if I need to take the site down and call the experiment over to avoid copyright infringement or other laws, or if it's "safe" to let it keep going. What determines the difference between aggregating and content theft?
