That had nothing to do with anything. She ended the gig because of other reasons.
Watch her final cam shows and she will explain it.
Yes. The way it was explained to me was "Crave You" was somewhat of a breaking point for how videos were conceived and directed. Up until that video Mumblez was a sort of lead, or co-lead, in the creation process. The shoot was apparently quite contentious with lots of squabbling. After that, Mumblez backed off and let Nikki take the lead, and to be honest, some of the best videos they did were post June 2016. "Bubble Bikini," "Squirting Good Time," "Glass," "Spunky," "Shake Weight *******," "Road Trip" and "Mesh Suck" were predominantly Nikki-led videos (with Mumblez sometimes shooting and providing advice on blocking of the action). This put all the onus on Nikki to develop and choose the structure and limitations of the content.
After a while, the grind of having to always produce content within the bounds of their comfort-zone led to tedium. On top of this process-fatigue, there was the added issue of constant criticism from Freeones (which frankly provided the majority of their feedback outside of the group chats, twitter and innerdeviant [which were predictably fawning]). They had no one to talk to who could provide unbiased advice or share their frustrations with; their peers from the solo non-nude model world had either become estranged or had closed up shop. The final nail in the coffin was the death of affiliate marketing and the proliferation of tubesites and porn piracy boards poaching their content within 24hrs of release.
In summary, the reasons for Nikki's retirement were:
1) It was no longer fun
2) There was too much criticism
3) The easy money dried up and thieves took the rest
The twitter rant that Nikki posted years back were in some part her own thoughts but in many ways were the expression of Mumblez' frustration that were voiced through Nikki (as she had a bigger platform on twitter than him to voice said). She definitely wanted a break. She was fed up with all of it and wanted to see if time away would rekindle her interest or if it would lead her to finding something new. After 8 months away she was essentially convinced that she wouldn't be returning. The business had changed and it was no longer aligned with their interests and values.
Now, why is it that they have gone silent since May 31st? No idea. Seems abrupt to me. Don't know what triggered it. I can see it being a simple matter of cost, perhaps, or may be just a full and complete burnout on it, but I really can't say for sure. Of course I would appreciate getting a sign-off or at least some sort of formal goodbye. but in lieu of that, I hope the best for them.
