Hello @marcella, this extension came up as a Code Stewardship review request, but I've noticed that it is marked as being stewarded by the Editing team on developers/maintainers page. Just checking to see what the actual Code Stewardship status is before I dig any deeper.

@marcella: Could you please elaborate if the WMF Editing Team is responsible for the SpamBlacklist extension? Thanks.

This extension is not currently maintained by the WMF Editing Team. We have no specialized knowledge or skills among the team engineers to support this extension. I'll update the developers/maintainers page to reflect that we are not actively maintaining it.

The form seems a little underfilled out... There was basically one production error which arguably was intentional behaviour (albeit maybe a poor design choice not to suppress it)

Still waiting for a code review 1+ year later at https://gerrit.wikimedia.org/r/c/mediawiki/extensions/SpamBlacklist/+/505688.

At the Wikidata project, we have been struggling to use this extension as it does not seem to behave as documented. We add URLs to the blacklist and the API confirms that they are blocked, but editors can go right ahead and add them anyway. See T251047 where this was reported a year ago, but we still have no guidance on whether we should even keep attempting to use this anti-vandalism tool.

Removing task assignee due to inactivity, as this open task has been assigned for more than two years (see emails sent to assignee on May26 and Jun17, and T270544). Please assign this task to yourself again if you still realistically [plan to] work on this task - it would be very welcome!

For everyone's info, currently no Code-Stewardship-Reviews are taking place as there is no clear path forward and as this is not prioritized work.
(Entirely personal opinion: I also assume lack of decision authority due to WMF not having a CTO currently. However, discussing this is off-topic for this task.)

Note that the work on T279275: Move all the functionality of {Spam,Title}Blacklist extensions into AbuseFilter and retire them, if completed, will mean that this extension is undeployed from Wikimedia, un-bundled from MediaWiki, and likely archived (unless someone comes along to support it).
