This is a follow-up to the discussion in T341599#11502003.
On Spanish Wikipedia, Special:Impact is currently localized as “Especial:Incidencia” (/wiki/Especial:Incidencia).
As explained in the linked Phab comment, “Incidencia” is a false friend and incorrect in this context. The page measures positive user impact (edits, thanks, streaks), so “Impacto” is the correct and natural Spanish term.
In addition, “Impacto” is already used in the page title and in other parts of the UI, so the alias should be consistent with the rest of the page.
Please update the eswiki special page alias accordingly.
Thank you.
