I can't accept the fact that I spent 30 minutes trying to figure out how to block a domain on Gmail. And failed. Shouldn't it is something like right-click -> block -> an input for the email or domain? Am I asking for something unreasonable here?
Update: apparently you can create a filter (the option also is hidden in the settings). While it works in practice, I still can't accept that there is no option to block a domain in Gmail...
