Requests are unidentifiable severe
Feed requests appear to be associated with this app but can't be accurately identified.
Why it's a problemA feed reader that can't be identified is often unfortunately used in ways that are severely abusive to a website, either intentionally by malicious users or unintentionally by its users who may be unaware. Since this application is unidentifiable, there's no way to validate its requests and mitigate any potential abuse.
What it means for usersWebsites are likely to block or severely limit this app from their feeds, causing feeds to behave unexpectedly or not work at all.
How to fix itThe application or its usage needs to be verified, which will remove any limitations or restrictions, and feeds used in the application will be much more reliable.
Too many requests to non-existent content critical
A large number of requests are being made by this application for feed content across websites where no feed content exists.
Why it's a problemIt causes unnecessary strain on websites and can negatively impact their performance. Because bad bots often behave in this same way, websites will likely block the app for being associated with this activity, regardless of the application's intent.
What it means for usersWhen a website blocks this application for this behavior, feeds will stall or stop working entirely.
How to fix itThe application should reduce the number of requests being made to pages on a website that don't exist, and consider using the website's site map or robots.txt file, if available.
