Well I did just get this message from Tumblr Support yesterday.
The video you posted on Apr 29th, 2016 8:16:07pm was removed for violating our Terms of Service and Community Guidelines, which you can skim over at:https://www.tumblr.com/policy/community
Long policy short: we don’t allow sexually explicit videos to be uploaded to Tumblr.
If you think there was a mistake (it happens), you can submit an appeal here.
You’ll need to provide the URL of the removed post:
After too many violations we’ll have to terminate your account — and nobody wants that.

So that could be it I guess but not sure about the other videos that I just noticed are not working either because this is only the second message from tumblr I have received so far. The other one was for the threesome MLP longer animation I did way back last year and it was only for the preview.
Not sure what is going on right now and with the dmca stuff coming from Blizzard on Overwatch models in SFM happening now, I am not sure what to do. And I just got a message from a patron saying that Blizzard is sending out DMCA notices to people using the Overwatch SFM models. I have not gotten that message myself but I am kinda at a lost on what I should do at this point. This could be the beginning of the end peeps…
Finally that policy is getting enforced.
Come on, it's not that hard to put it on another site. You could even put a teaser GIF (which I'm pretty sure is not a video).
