Scrapping financial newssites

Hello,

I am trying to create an automated newsletter from financial newsfeeds, such as:

• http://feeds.bbci.co.uk/news/world/us_and_canada/rss.xml
• https://www.theguardian.com/international/rss
• https://www.cnbc.com/id/100003114/device/rss/rss.html
• http://rss.cnn.com/rss/cnn_topstories.rss

I am scrapping all these news and then use a summarizer to create a short overview, with a source link.

However, for some of these feeds I get no articles-content back. I am currently using the wordpress automatic plugin to fill my post pipeline.

1. Do you know if these newssites are actively blocking scrappers?
2. Are there any other sources for financial news content that can be scrapped?

Appreciate your replies!
