I never even heard of this website/magazine and even they have a Paywall.
It's almost as if their desire for getting paid for their work is unrelated to your awareness of them.
I mean, what's an extra $120–$299 per year to subscribe to this website, especially when it's of such high quality that it already has
> 5,00,000+ subscribers [sic]
?
It looks like the website is based in India.
Instead of the ones(10^0)-thousands(10^3)-millions(10^6)-billions(10^9)-... system followed in most other parts of the world, the Indian numbering system uses ones(10^0)-thousands(10^3)-lakhs(10^5)-crores(10^7)-...
So, for example, half a million subscribers (500,000) would translate to 5 lakh subscribers (5,00,000).
Seems to be using the Indian numbering system:
It's the Indian English convention for placing commas in numbers -- one comma after the first three digits, then one comma after every two digits thereafter. e.g.
1,23,45,67,890.
