No. Firstly, there was no "leak", the data was never shared. The experiment was conducted by researchers then the data set destroyed. Secondly, there's 3.5b WhatsApp accounts. They just send the same message to everyone and the majority of numbers will have an account regardless.
I assume it can be related to this leak? Knowing someone uses a service can increase the effectiveness of targeted phishing.
Interestingly it’s harder to block these senders that do not advertise a number on sms.
