I think it is a good opportunity to also enable range block: $wgAbuseFilterActions = [ 'rangeblock' => true ];

Rangeblock does block the entire /16 IPv4 range of the triggering IP for
infinite, and I'm not sure if it does support IPv6 nor if it respects
BlockDuration/AnonBlockDuration from abusefilter.php. Maybe we should
investigate that first.
