I have personally set a standard or a set of rules for writing Hindi using English alphabets myself and I have seen my friends follow the same. We do not use such shortcuts/shortforms.

Is their true identity a secret? If not, can someone please point me out to their real name. I am just curious about their profile and would like to have a look at their LinkedIn or Twitter if they are on there.
I do not wish to pry open anyone's anonymity and so if their identity is a secret, I am fine with that. I honestly just want to have a look at their journey which sometimes LinkedIn / Twitter / GitHub / individual blogs provide.
