Current scenario
To allow for appeals, global IP blocks do not apply to Meta-Wiki.

However and seeing how the vast majority of blocked IPs come later to Meta-Wiki to continue to vandalise, it has been customary for some time already to issue at the same time a local block mirroring the global block settings. To do that, we have a checkbox on Special:GlobalBlock (introduced at 581a1aa161a6 as per T19824: Optionally place a local block when globally blocking) that makes mirroring the global block to Meta-Wiki easy, but has a major flaw: it blocks talk page access by default (cfr. T146120: Do not block talk page access by default when setting a local block on Meta) therefore blocking all means of communication. Despite of that, it is a heavily used feature, which demonstrates, IMHO, that there's a recurrent need that such global blocks be expanded to Meta-Wiki as well to prevent further abuse (v.gr. continued abusive account creations or vandalism).

Requested scenario
It is therefore proposed:

• That global IP blocks do apply on Meta-Wiki by default.
• Talk page access for globally blocked IPs is kept revocked.
• Talk page access for globally blocked IPs for Meta-Wiki only is kept open. This is a must-be. The blocked IP should be able to edit only the Meta-Wiki talk page (other options such as creation of accounts should be kept blocked).
• That a checkbox to optionally not apply the block to Meta-Wiki be added instead.

Thank you.
