How come when asking a question and checking notifications checkbox you can enter any email in the text field nearby? Doesn't it mean that I can write any email of other SO user (or generally any email) to simply spam another person? Are there any counter measures against that?
The funny thing is that every hapless user you do that to, has the ability to turn off all your email notifications with a single click.
(the link is included in every email that goes out).
So you'd have to go in and re-tick the global email notifications box every day for this sort of griefing to work. You'd almost be griefing yourself, really.
I would imagine that this would fall under the banner of objectionable behaviour (aka the Penalty Box).
