This is one of those things where, in a world where no one trolls, it would be a great feature. However, I do not trust people not to troll others. I'm guessing the devs don't either. For everyone's sake I feel that this feature should not be implemented. Considered? Maybe. But the pros and cons need to be weighed, along with an assessment of how people treat others on the internet, and it doesn't take a rocket scientist to figure that part out.
