Wait, why? If the edits were so clean and uncontroversial, what was suspicious?
Sorry for asking, the wiki talk-page links very chaotic to read.
There are little behavioural nuances in your writing or the timezones/subjects in which you edit. Using multiple accounts is mostly forbidden by Wikipedia policy, unlike most websites, so just proving the link can be enough.
Icewhiz is a bad example because a lot of the evidence is non-public now (there's a cabal of CheckUsers approved by the Wikimedia Foundation who deal non-public cases). A simpler one is Lieutenant of Melkor/CaradhrasAiguo. Lieutenant of Melkor was banned in 2014, CaradhrasAiguo was made in 2015, and in 2020 someone linked the two accounts:

> Editor interaction tool shows 2691 common pages. This is because both have been AWB power users in several same topic areas. However, there are numerous specific commonalities with extreme detail related to American cities, Chinese cities, weather templates and airports.
> Both used navigational popups to revert edits which resulted in a non-standard date format in the edit summary.
> LoM created many US city weatherbox templates. CA has been the only editor to do major updates in many of them.
> Both have done major work with pushpins related to Chinese maps. 'Pushpin' is found in many edit summaries of both editors.
> Both often removed bold text from non-English words. Both used edit-summaries with "debold" which I don't think is a real word.
> Both updated snow days and precipitation days in US city infoboxes with almost identical edit summaries.
> Both have an interest in classical music. CTRL+F for Beethoven, Mozart or Chopin in the editor interaction tool.
They're also both named after Lord of the Rings characters. "Caradhras" is a mountain, "Melkor" was the most powerful Valar and later went by the name "Morgoth". Sauron, the antagonist of LotR, was his lieutenant.
