I made an edit to the page although now I'm not sure - is this page supposed to be specific to metawiki itself?

So this is only true for en.wp then? https://en.wikipedia.org/wiki/Wikipedia:User_access_levels#User_access_level_changes

A related question regarding someone who lost their ability to upload and move files (which I suspect is because they lost their autoconfirmed status, and I confirmed that through UserRights special page):

1. is there a log somewhere that logs when and why a user lost their autoconfirmed (and if not should there be one)? Because I looked again at my faulty filter, and one particular user was not losing her right because of that filter, so I can't answer her as to why she lost her status (since it cannot be done manually by an admin either right?)
2. if indeed the 'confirmed user' is not available in all wikis, is there a way to re-grant (auto)confirmed status to my local wiki (id.wp)?

@Krenair: the stewards bit is not true, though. I'm a steward, and that option was still greyed out for me (on id.wp), but I have that option on meta, though (where I'm not an admin, so it's must be my steward flag)

No, you're not a steward on idwiki: https://id.wikipedia.org/w/index.php?title=Istimewa:Daftar_pengguna&group=steward
You're a global steward. You can use interwiki-userrights from meta because you are in the local steward group on meta. (obviously, you can use this to assign yourself steward on any wiki from meta. This is currently required for performing certain changes) Perhaps this difference seems silly to you but it matters from a technical point of view.

No.

Presumably Special:AbuseLog? As far as I know, admins can't revoke it manually.

2. if indeed the 'confirmed user' is not available in all wikis, is there a way to re-grant (auto)confirmed status to my local wiki (id.wp)?

Community consensus could give legitimacy to a Wikimedia-Site-requests task allowing local idwiki admins to grant the 'confirmed' group to users.

Thanks for the confirmation and T101983, I'll wait for it to be resolved instead.

Does reverting the actions by the abusefilter through [[Special:AbuseFilter/revert/$id]] work?

Yep, works for me.

Edit: Works because of https://github.com/wikimedia/mediawiki-extensions-AbuseFilter/blob/master/Views/AbuseFilterViewRevert.php#L213 (grep does not necessarily reveal this because of the case of that P)
