During Wikimedia-Hackathon-2023, local spamblacklists (MediaWiki:Spamblacklist) was largely converted into a Special:BlockedExternalDomains page, which is much easier to use and work with, even without regex knowledge. However, this migration does not impact the global spam blacklist, which is controlled from Meta-Wiki (see the link before).
Within this task, the global spam blacklist should be integrated with Special:BlockedExternalDomains as well.
