You are jumping to conclusions. The author is the CTO of the largest online brokerage in India but more importantly, they have created many open source software of good quality. His website and blog are of great quality. Whether you think this library deserves more attention or not is your personal preference but it is far from spam. I havr no affiliation with them but like their work.

It's possible for both things to be true: this project is written by a developer well-known within India, AND this thread has a lot of bot (bought?) comments of praise in it.
