Primary task for deploying the [[ https://www.mediawiki.org/wiki/Extension:StopForumSpam | StopForumSpam ]] extension to Wikimedia production.
[x] Add the new extension submodule to the git mediawiki/extensions repo (https://gerrit.wikimedia.org/r/101014)
[x] Add extension to the make-wmf-branch release tool (https://gerrit.wikimedia.org/r/650167)
[] Security review (likely unneeded in this case)
[] Move extension CI config to wikimedia-deployed section
[x] Deploy to beta cluster and evaluate (T181217)
[] Performance review (T266904)
[] Set `$wmgUseStopForumSpam` to `true` (and other relevant config e.g. [[ https://gerrit.wikimedia.org/r/c/operations/mediawiki-config/+/521233/4/wmf-config/CommonSettings-labs.php | this ]] and T273211) for pilot production wikis[0] in `InitialiseSettings.php`
[] Update https://www.mediawiki.org/wiki/Extension:StopForumSpam ("Release status" etc)
[0] A group of initial pilot wikis will need to be determined, perhaps ptwiki (T261133) and others?
Also, T255208 needs more work including the likely addition of informal methods of evaluation (admin surveys, etc)
