I've got a few of Google Alerts set up based on a site. The alerts are set to "All results" (and not "Only the best results"). For example:
password dump site:pastebin.com
I use the above to track data breaches and collect passwords for my password lists.
"I use" is a misnomer because I've never gotten an alert even though there are lots of hits when searching. I've got similar alerts for different sites (like the National Science Foundation,
nsf.gov) and they have never fired either.
How do I set up an alert with a site filter?
