When the community approved and requested in T54681 that AbuseFilter should be able to block users at Meta, we forgot to ask the change of the configuration settings to allow Meta-Wiki admins to use the feature. It happens that "block" is a restricted action and Meta-Wiki sysops do not have the 'abusefilter-modify-restricted' usergroup.

As such, I am requesting that the following rights be added to Meta-Wiki administrators (along with other changes non controversial changes such as the ability to revert changes and view private filters [this one is default to all sysops] to make this feature avalaible:

$wgGroupPermissions['sysop']['abusefilter-modify-restricted'] = true;
$wgGroupPermissions['sysop']['abusefilter-revert'] = true;
$wgGroupPermissions['sysop']['abusefilter-view-private'] = true;

There was community discussion in december last year, but I guess that since it was a single minor incident, nobody posted this here. However today trying to do maintenance on some filters, an error message appears telling me that I do not have the appropriate permissions. I think it would be overkill to ask the stewards each time a local filter with a restricted option needs to be modified.

And passing by, please modify the following:

$wgAbuseFilterBlockDuration = 'infinite';
$wgAbuseFilterAnonBlockDuration = '31 hours';

The first one is no real change as it is already default in the global configuration. The second one is to prevent the filter blocking IPs forever, blocking them for 31 hours instead as it is standard practice on Meta.

If you have questions please do not hesistate to ask. Hope to have posted this correctly. Best regards.
