These are not tumblr specific policies. Tumblr is implementing age verification in response to legislative moves that were made months ago.

If you did not know this was happening, you were behind the curve. That is fine. You're caught up now. The next step is to link up with people in your country who are working to preserve privacy, to roll back these laws where they exist, and to prevent their passage where they do not.
