That's already implemented: T398626: Create a default expiry option for blocking Temporary Accounts – mw:Manual:Block and unblock#Default block duration options

You can specify the desired duration via https://he.wikipedia.org/wiki/מדיה_ויקי:Ipb-default-expiry-temporary-account

for WMF wikis - 3 months

Several wikis (en.wp as a particular one) actually block temporary accounts indefinitely. This has utility for mark blocked user scripts and in general sockpuppet hunting.

My opinion is that a button that says indef should mean indef, regardless of user kind and as such this task should be declined.

Interesting. Can you please explain why is this the habit in the enwiki? Is this only a matter of convenience (which is what I suggest to change in this task - I suggest that the most accessible button will be block until 3 months - expiration date of the temporary account), or maybe this is done for the sake of having some documentation for the future?

I don't suggest that a button that says "indef" will block for a shorter time. My suggestion is that instead of the button "indef", there will be a button that says "3 months"', because there is no need to spam the blocked list with temporary users.

or maybe this is done for the sake of having some documentation for the future?

This, personally it's useful to establish block evasion. If the user behind the temporary account is editing again, then the 3 month expiry means that it's harder to say that the user evaded their block (because the block since expired)

My suggestion is that instead of the button "indef", there will be a button that says "3 months"', because there is no need to spam the blocked list with temporary users.

This radio option was added recently and was specifically intended to be indefinite. Whether this was intended to be indefinite for temporary accounts is a different matter, but it seems this varies wiki-by-wiki. Therefore, I would suggest that this be configurable per-wiki instead of replacing it entirely

Hello @neriah

For Tech News: What wording would you suggest for the content, and to confirm, is the week of June 15th the intended week for the announcement?

Something in the style of this:

Wikis that wish to replace the "indefinitely" button in Special:Block for temporary accounts (for example, wikis that block temporary users only until account expiration) will be able to do so by creating [[MediaWiki:ipb-indefinite-expiry-temporary-account]] with the desired block duration value.
