Give back the option to block domains!!!
The 1000 limit on blocked address can not keep up with the computer generated amount of spam addresses. Bring back domain blocking!!

You can STILL apparently block domains.
On the right side of the screen click the gear icon, and choose "more settings"
Click on "Privacy and Security"
You have a list of "Blocked addresses"
Click on the blue "+ add" then enter the email address OR domain you wish to block to the right of that column.
I use "*@ac-orleans-tours.fr" (minus the quotes) as an example.
If you leave off the asterisk or the @ sign it will tell you "the address is invalid"
