Adding "@username" format

Substack changed the default presentation of user profiles to show the "@username" in the URL instead of the numeric id. The numeric ID can still be found with more technical means probably, in for ease of use extending the regex to allow for both seemed like the most simple solution. Kristbaum (talk) 22:00, 14 September 2023 (UTC)

I would also like to see this addresses.

Unfortunately the URL formats are different for handles vs IDs.

For example: @billwillingham doesn't work in the profile url https://substack.com/profile/@billwillingham

I wonder if we can follow what we do for YouTube where some bot takes the channel name and converts it to channel ID. https://www.wikidata.org/wiki/Property:P2397 RayScript (talk) 09:03, 15 September 2023 (UTC)

Unfortunatelly now any items using '@username' style IDs don't work with this property. Perhaps splitting into two properties, like YouTube's YouTube channel ID (P2397) and YouTube handle (P11245), is in order. Trivialist (talk) 02:24, 21 September 2023 (UTC)

Or this can be solved by allowing both syntaxes (distinguishable by the format) and choosing the proper destination URL in a linking helper (cf. e.g. https://wikidata-externalid-url.toolforge.org). --Mormegil (talk) 15:42, 22 September 2023 (UTC)

In the meantime, how do you find the numeric ID? Profiles URLs that I see are in the form https://substack.com/@profile and I have no idea how to get the equivalent https://substack.com/profile/123 format? Nclm (talk) 10:43, 27 April 2024 (UTC)
