There is a consensus by the global Wikimedia community to enable global abuse filters on all Wikimedia projects, except projects that explicitly opt out. Global AbuseFilters are already enabled on small/medium projects; we now need to enable it on all large projects (except those which explicitly opted out). This will help Stewards and Meta administrators to better engage in countervandalism.
More details about the approved proposal are at https://meta.wikimedia.org/wiki/Requests_for_comment/Make_global_abuse_filters_opt-out.
