Change 910788 had a related patch set uploaded (by AGueyte; author: AGueyte):

[mediawiki/extensions/AbuseFilter@master] Prevent CannotCreateActorException on first time editing Talk Page

https://gerrit.wikimedia.org/r/910788

The patch lifts the block on creating your talk page as the first edit while having a block against your IP from AbuseFilter.

This is a workaround to address the error of IPs blocked by AbuseFilter and anon users first edit being their talk page.

This allows them to edit their talk page and create their temp account username.

• Yet, this doesn't prevent the log to show the talk page IP: "*Unregistered 27 talk contribs created page User talk:172.18.0.1 (test)".

An issue that is also mentioned in T334623

• It also doesn't address the actual block against the IP by AbuseFilter
