Domain Blocker

[#1]

Is it not possible to have the option of blocking a domain with a single click ?
I have often marked items as spam but still keep getting them, yes I know it's possible to go on some page or other and enter the address or addresses you want blocked but it would be much easier if it could be done with a single click.

A single click is too easy and someone may well make a mistake. Then you've got the issue of people not knowing what they've done and how to reverse it.
Anyway, I thought it was quite simple enough to add a domain to the black list, not just an address. That's assuming those settings are still active with the newer anti-spam platform?
