Some sites (e.g. https://www.jwz.org/blog/) have started returning errors when receiving unsupported query arguments, like _.

Background / motivation: https://www.jwz.org/blog/2024/06/blocking-bogus-url-parameters/

These errors have started showing up in my NewsBlur feed for this site.

Could you confirm that NewsBlur is added the _ query argument? Could that behavior be removed or at least made configurable?
