Why "dating" spam from India.
There's a reason (not an excuse) for the dating spam from India.
If you look at: https://www.populationpyramid.net/india/
and click on the blue/red bars to see the underlying numbers, you'll see that there are about 23,000,000 (23 million) more men than women between the ages of 20 and 39 in India.
(The trend continues in older and younger groups too.)
So there are 23 million men, in the prime of life, "left over" (or "excess") even after all the women have obtained a boyfriend or spouse.
23 million men, more or less without hope for a partner. Can you imagine the competition? The desperation?
The situation arose because of "sex-selection abortion" (now outlawed there, but not completely eradicated) and some reported infanticide (always been illegal).
At the root is a preference for sons, and the tradition of parents having to provide a dowry for daughters.
The corrolary, if that is the right word, is that single women in other countries could possibly find spouse candidates among those 23 million "extra" men in India, if they have no luck in their own country.
And as far as I know, there probably are some legitimate global match-making companies taking this into account.
And... If you look at China's numbers: https://www.populationpyramid.net/china
they have the same problem, to a slightly smaller degree, due to their "one child policy" which has now officially ended. But the gender imbalance in those age groups that were affected will linger on.
I put this forth just as a "back-story" to the spam, for those not aware of the population demographic matter.
