This might be a duplicate bug, but...
The fundraising banners apparently have an obscure opt out system currently. It's described at https://en.wikipedia.org/w/index.php?title=Wikipedia:Village_pump_%28miscellaneous%29&oldid=461156874#How_to_hide_all_fundraising_banners_on_all_Wikimedia_wikis_until_next_year.
There should be a proper UI for this kind of thing. Either a Special page or something similar. Envisioned workflow:
- user clicks "x" on a banner
- small pop-up asks "do you want to hide all fundraiser banners? y / n"
- clicking "y" leads to a confirmation page (probably with the obligatory begging)
- clicking "n" leads to the small banner disappearing; banners will resume within a week (or whatever the current timeout on the dismiss cookie is)
I don't think adding this to the UI will make it any less of an advanced feature than URL magic. That is, I think the same people who would use the URL magic will use the interface. It's just a cleaner, saner way to do it.
