The Facebook-owned messaging platform WhatsApp is the leader in the Brazilian mobile messaging market, surpassing 100 million users. Brazilians have long ceased to use SMS messaging as a means of daily communication. The strong presence of WhatsApp is favoured by some telecom companies delivering the service for 'free' in the zero-rating model, in which the app doesn't use a person's data.

Hence, the multiple recent bans on WhatsApp' services ordered by Brazilian magistrates ignited widespread discussion. Currently, the platform has been ordered to suspend its services four times, with law enforcement authorities arguing that the company hasn't released to law enforcement user data which was deemed fundamental for criminal investigations. The issue recently escalated with WhatsApp adopting end-to-end encryption by default to all its users, meaning that, in theory, the company will hold no user content data.


The conversations themselves are usually what you would expect if you had spent a moment thinking about spammers themselves, but they were surprising to me, because I hadn't. Spammers will usually realize they're talking to a bot (or at least to someone who isn't interested or not going to give them any money) after around 3-5 messages, but some have sent up to 15 messages before giving up in frustration.
