WhatsApp takes bot spam very very seriously, and as a result, there is zero bot spam.
Before you can sign up to build a WhatsApp bot, you need to jump through a million hoops, and after that, every automated message template must be vetted by Meta before it can be sent out, apple style.
I'm glad of this, because unlike SMS and other messaging platforms, WhatsApp is spam free and a pleasure to use.
WhatsApp is certainly not spam free. I get spam over WhatsApp, less than on telegram but still more than zero.

At least here in Italy whatsapp is a spam house unless you actively update the default privacy settings in-app. There is no discernable difference between SMS and WhatsApp to spammers.
