@Urbanecm Sorry to bother you again, but I thought that a mere adding of abusefilter-modify-restricted right to the abusefilter group would give the Abuse Filter ability to perform "block" actions. Apparently that's not enough. My fault, I'm sorry.

Therefore I would like to kindly ask you to add to the wmf-config/abusefilter.php the following lines:

$wgAbuseFilterActions['block'] = true;
$wgAbuseFilterBlockDuration = '2 hours';
$wgAbuseFilterAnonBlockDuration = '2 hours';

The specified time wasn't discussed in our Village Pump discussion, but 2 hours is more than enough for us to stop a vandal and if needed, to reblock them for a longer period of time. To further clarify, the discussion in our village pump wasn't only on adding the "abuse-modify-restricted" (which is already done, thank you!), but on giving the AbuseFilter the ability to block (headline: "Możliwość blokowania przez filtr nadużyć" – "The ability to block by the Abuse Filter"). The "abuse-modify-restricted" is mentioned there only because, like I said, stupid me didn't look into details and thought it was sufficient to get that blocking ability.

Thank you in advance
