I think if you are too cowardly to even use an unidentifiable user name, you should lose the right to block people. If you want to troll and block people from saying you're a troll, you should have to identify yourself at least with a user name!
Defenders of anonymous PRIVILEGES to block the identified user are like zionists: what's mine is mine and what's yours is ASSUMED to be negotiable.
They should pay the price for hiding their identity. No one can harass an anonymous person, only disagree with them, so why should the anony care what people say on the thread?
While I can see a real need to go anon on occasion, it seems to be horribly overused and abused on this site. I'd be for anything which discourages its use, even if it means forfeiting the ability to block answers on a question.
I think all the people you block (as a regular user) are automatically blocked from answer on any of your questions whether you ask them anonymously or not. That is to say, you don't lose user rights by going anonymous and frankly I don't see the point in penalizing people for asking something anonymously... most anonymous users are probably not trolls?
I think GAG should make it so you can't post questions on anon. So if you say something about men or women you have to admit to who you are. The only topics that you should be aloud to post anon questions on should be "sexual behaviour" and "sexual health" and if you post anything that is not a sexual related question in those topics it should be moved by mods and admins to the correct topic and your identity should be shown. If you are going to post questions on here you should have to show who you are, excluding in sexual questions.
I very rarely go anon myself--normally so I can say something without sounding like I'm bragging--but I never block. I only ever find out about blocking when I'm trying to pay a compliment to someone about a great opinion, and a message pops up saying I can't. . . because they blocked me! And normally I have no clue who they are.
There is too much anon on GAG, like ridiculously so. Anon questions and opinions which are totally innocuous and run of the mill. It's a bit strange.
