I am using desktop app import.io
I have two extractors, one is scraping list of 10 links and some text, and another extractor is getting data that are on pages of that links.
All was working perfect but after two days I got Cloud Flare protection that is checking browser. When protection is on it is sending cookie "cf_clearance" to browser.
I also thot that some other user are attacking that site, but I am not sure. After two days they turned off protection, then I tried my import.io extractor and they worked perfec but after 10min protection is again on.
I think when ever user of may mobile app is requesting data from import.io, that your app is sending request to my source data web page.
