Didn’t know about your ping-list, otherwise I’d have asked if this was worth your pinging it.
No prob! I scan posts each day for anything relating to illegal immigration, illegal immigrants, border issues, etc. ad infinitum; and add the keyword ‘aliens’. Then I ping one article I find interesting or different from all the rest. The ping includes a clickable link to a list of all posts with the ‘aliens’ keyword.
If you think it deserves notice, add the keyword and voila...it’s on the list!
