Today, 6/1/2017, I received this message from Yahoo in my Yahoo e-mail account inbox:
Hi Anne,
...we prevented a sign in to your Yahoo account...
Date and Time: Thu, Jun 1, 2017 10:19 CDT
Location: United States (IP Address: 107.30.161.118)...
This is the 9th sign in attempt that I have received in as many days, but only the first for this particular IP address. I will be filing separate reports for the other IP addresses Yahoo has reported to me (3 others).
