Is Bad URL Killer safe?

Low risk

Bad URL Killer sends the full URL of every page you navigate to, plus a persistent install ID, to cloudoneth.free.nf.

To check each site's reputation, the extension sends the complete address (path and query included) of every top-level navigation, along with a random per-install ID synced across your devices, to a free-hosting domain. The server replies with a 0 or 1 verdict; a 1 blocks the site and clears the page with a warning overlay. The server can also redirect the active tab to its own service URL.
