How to block junk domains that redirect to ladsblue.com?

There are tons of such .fr / .de sites, and if you click these search r###lts, you are redirected to ladsblue.com (a famous malware domain).

I don't know how you can determine from the r###lts page where a domain will redirect.

I know "someday" it would be great to have a feature in this script to filter based on the text snippet for the search r###lt, and not just the domain, but I don't expect to have that for a while. Also, maybe the snippets for these r###lts is innocent because the site doesn't redirect the Google-bot, only normal users, or the behavior changes after indexing. ??

Maybe a separate add-on or script can retrieve the URL in the background and see whether it triggers a 301 or 302 redirect. Detecting a redirect in the HTML or a script seems a bit complicated. Do you know of any online services that might have that kind of information?
