It was shown on this page:

And the little chart there clearly showed that ADULT (not just NSFW) blogs would not get indexed by search engines.

But now it looks like they are changing something as this appears at the top of it:

"This Page is out of date and is in the process of being updated."

I guess maybe I'm not quite clear on what they are really going to do and I could be missing something but the above is definitely true. It will be great if they are really going to stop putting all adult blogs (not NSFW) as disallowed in robots.txt.
