Block spam better. Somehow with all of these breaches, I am hit with 100’s of spam emails and some are in different languages. I am also receiving “extortion type” emails stating that they know my password and they have film footage of me. Total Lies and unappreciated. Other than changing my password again and again, when will there be a more secure Hotmail so our accounts aren’t hijacked like this?
