208/8 announcements

I am under the impression that the 208/8 network has not yet been
  assigned to anyone. It appears we are only up to 207.19/16.

  However, as someone (Avi?) pointed out earlier:

  Is anyone filtering these routes? From a customer perspective, I think
  it would be nice if my providers would do so.

  Or maybe these guys would filter them:

  I dunno, maybe I should filter them. What are other people doing?
