Based on Marco_Acortes' posts from 2013-2016, they appear to be a young adult, likely a college student studying STEM subjects (e.g., mentions of differential equations and finals). Content is mostly casual: daily life, friend interactions, humor, work complaints (e.g., Costco), music, and emotions. The 2013 "Corona virus" post may refer to MERS outbreaks at the time. They stopped posting abruptly in Dec 2016 with a smiley face; no clear reason evident.
Words fall short today.
Mr. Ratan Tata's
profound humanity and selfless compassion shall always inspire us.
He will forever be remembered as our beloved mentor.
