PREACH. This is hands-down the single largest reason why I abandoned my Gmail. I receive countless people's credit applications, loan details, new credit card details, bills, etc, credit collections, etc.

All because they have the same last name as me and opted to use a period in their email address.

This is happening across multiple countries as well. Sadly, none of these people ever receive their important messages because I gave up trying ages ago.

How they continue to explain this away as a feature is beyond me. Google is constantly pushing forward with various, and perhaps superficial, security/privacy oriented initiatives yet here's one of their core products offering up the most private details of others without zero care to fix it. SMH
