"A better, more positive Tumblr"
Most people used Tumblr for the nudity. I have a customer who has sent me 22 links in the last 3 days setting up our next roleplay.
I'm sure other elements like fandoms etc will be able to thrive, maybe? I had just started to get back into the habit of using it again for adult marketing. They've updated some features that made posting easier. Over the past several months, and inspired by our storied past, we’ve given serious thought to who we want to be to our community moving forward and have been hard at work laying the foundation for a better Tumblr. We’ve realized that in order to continue to fulfill our promise and place in culture, especially as it evolves, we must change. Some of that change began with fostering more constructive dialogue among our community members. Today, we’re taking another step by no longer allowing adult content, including explicit sexual content and nudity (with some exceptions).
None of my adult tumblrs have nudity on them but there are numerous references to camming etc. I wonder if those will get deleted?
We’re relying on automated tools to identify adult content and humans to help train and keep our systems in check.
This tells me that yes, yes my tumblrs will be deleted.
The part regarding the banning of adult content on Tumblr
Adult Content. Don't upload images, videos, or GIFs that show real-life human genitals or female-presenting nipples —this includes content that is so photorealistic that it could be mistaken for featuring real-life humans (nice try, though). Certain types of artistic, educational, newsworthy, or political content featuring nudity are fine. Don’t upload any content, including images, videos, GIFs, or illustrations, that depicts sex acts. For more information about what this guideline prohibits and how to appeal decisions about adult content, check out our help desk.

Female Presenting Nipples? WTF?
What is still permitted?
Examples of exceptions that are still permitted are exposed female-presenting nipples in connection with breastfeeding, birth or after-birth moments, and health-related situations, such as post-mastectomy or gender confirmation surgery. Written content such as erotica, nudity related to political or newsworthy speech, and nudity found in art, such as sculptures and illustrations, are also stuff that can be freely posted on Tumblr.
Ohhh sighs!
There are some low down dirty mutha fuckas in this industry. How could they ever think that tool would be a great idea? Why would Xbiz even put that article on their website to begin with? It sounds like a lack of integrity issue.
