Since the Abuse Filter supports global filters, Can it also support Global Blocking?
Edit 2017-07-06 by @MarcoAurelio:
Please investigate whether it'd be possible to let AbuseFilter to globally lock accounts and globally block IPs for users/IPs triggering a global filter. The global lock/block should be performed and logged at Meta-Wiki only. We've got some abusefilters that deal very well with spam and it'll save us a lot of time to have the filter do what we have to do later and manually.
