There is a user, who is consistently not quoting the references in their answers. Wherever there is a mention of the reference, it's not in form of quote but it's just a last line. (e.g. "Ref: Manusmruti, Srimad Bhagavatam").
Rarely their answers are quoted with source and is long enough not to be a comment.
I had an impression that we have pretty strict standards for quality from my personal experience in past.
What stops the Mods to delete this user's answer?
I assume that Mods may know about this user.
Yet they can see my last flag in the main site and they will already know.
As of today, this Avatar of Vishnu is reputed enough to see deleted answers of others.
