Eh, I would the say the ratio itself looks bad here. I am always surprised by how normalized and acceptable spamming is in the form of whatsapp forwarding. It's truly frightening watching my family use facebook and whatsapp groups. The spam to content ratio is like 10:1 or heck 20:1. Maybe even worse.

I am guessing you havent been on the internet 20 years ago when Indians were barely on the internet and email spam and forwarding was a huge thing.
The issue was solved by Google (and others) stepping up their spam detection game. The spam problem can and should be stopped with the technology, but I am not sure if Facebook has the motivations to do this.
