Tumblr's New Safe Mode Block NSFW Sites

[ptg]

Let's say there is an NSFW website blog hosted at Tumblr at the URL http://nsfwsite.tumblr.com. It used to be that you could visit that blog anonymously and view it. As of late, Tumblr has turned on a "feature" that blocks all such blogs unless you create a Tumblr ID and then configure it to turn "safe mode" off. That has implications for anyone using a stream capturing tool, since that tool may not run in your browser context and it is significant extra hassle to create a web browser session that logins to Tumblr prior to using that capture tool before you capture a stream.

If you visit an "unsafe" Tumblr URL you now get redirected to:
https://www.tumblr.com/safe-mode?url...te.tumblr.com/

Is there any way to form a URL to bypass safe mode manually, to avoid the whole need to create a Tumblr ID and configure its settings?
