I don't think we'll get any reply with that question. I was expecting something more... significant, or something more "important" like the title above seems to describe. Let me remind you that Mikael indeed visits this place but cannot answer every little questions like this. And he's rarely here, you need to be quite lucky to catch him and be here all the time (like I do).
And I don't think Mr. Akerfeldt have that much problems with privacy, unlike what Mr. Jackson had to live. Sure, he's famous somehow but it's not getting extraordinarily huge and over his head. On the contrary, being a new metal band I'd be happy if the world knew about what I do. In this domain, gaining popularity is sure useful but all that really matters is the art of music. Privacy issues are for Hollywood.
