I wish that a boo-boo button existed. Occasionally one of those box pop-ins - such as when you go to a site and it asks for your permission to allow them to access your location or something else. You click either 'allow' or 'block'. I always click block. But twice by accident I clicked allow, realized immediately my mistake, but could do nothing about it. Both times the amount of spam I received increased significantly so that I can't help but think it had to by my accidentally clicking on allow. Also, both times, if there had been a boo-boo button, I could have clicked on it to bring that last thing I clicked on to return, so I could switch from 'allow' to 'block'. I'm probably not the only one who like that option.
