In the Rambler banned (spamo) professionals.ru! Thank!
I express my deepest respect to Rambler and Pavel Rogozhin personally for putting malicious spammers and rare freaks in the face of the Professionals.ru team on their black list .
I really hope that other popular email services will follow their example.
UPD2: Still, social media is power! Professionals.ru stated that they completely refuse any letters to people who are not registered in the service, except if the letter is personally and consciously sent to another person by the service user. Let's see how they fulfill these obligations.
