1. Your comment

Some entries for Norwegian websites had been outdated for around 5 years each, possibly longer, so I attempted to remove those entries. I also detected 6 other entries that had duplicates within the same file (foreign.txt), so I de-duplicated them accordingly.

(The "Allow edits by maintainers" button for this PR has been turned on, of course.)

2. Screenshots

All involved factors involve only the PR's file change view below, to the best of my current knowledge. As such, a screenshot would merely be a copy of the file change view.

Hm. I don't see finn.no rules in Finnish or your filters.

[DandelionSprout]

The site received a massive complete overhaul a year or 2 ago, so older entries are simply not needed in any way.

I have finn.no##.banners in Nordic Filters at least, from what I can see. And more than 20 other entries.

Further clarification: Of the 7 entries that are commented on, only finn.no##.banners.adsbox still matches anything at all, and even then only on the frontpage. The other 6 entries aren't matching any elements at all.
