I would be more concerned if a human rights watchdog didn't have critics.

In this case it is simply blocked by category of "Advocacy Organisations". I mostly find peoples reactions interesting when I tell them that my school blocks human rights watch, we are not in North Korea after all... I am more sad about the block of "uncategorized sites" which my own site that I recently set up sadly falls under :(.

Keep it for a while so it’s not “new” and I think you will find that it changes category. (My own experience with a similar setup.)

This approach depends on not being in a rush.
