Wikipedia:Long-term abuse/Indonesian "stub"-related vandalism

Basic information
The Indonesian "stub"-related vandal refers to an IP user, or multiple users, from Indonesia that have persistently disrupted the English Wikipedia because the edits seem to be innocent or test-like, and most of the time they are ignored by recent patrollers.

Targeted areas, pages, themes
Nothing definitive, but mainly TV networks, telecommunications, languages, Wikimedia-related articles, years, territories, asteroids, passports, navigation boxes and stub-related templates.

Habitual behavior
The user (or users) started in January 2021. Mainly, the user adds nonsensical templates or statements to pages. In some cases, the tagged article cannot be considered as a "stub"; in others, the stub is unrelated to what they claim it is. The edits can be the combination of either:


 * Adds already-existing stub templates.
 * Adds the template code of inexistent stub templates.
 * Or the combination of both.
 * Adds the template last edited by.
 * Adds the template distinguish.
 * Vandalizes template pages.
 * References to "nursery rhyme".
 * Harasses editors.
 * Nominates pages for speedy deletion, and then proceeds to request the page to not be deleted. /

Cases

 * ANI report

Known ranges
As the IP ranges are highly populated, note that not all the edits are performed by the same person and they should be verified accordingly.
