Fine-tuning is pretty cheap compared to the original training run - perhaps just 1% of the cost.
Totally within reach of a consortium of.... "entertainment specialists".

Sure, it's peanuts compared to what it must have cost to train stable diffusion from scratch. However, I think most normal people would not consider spending $500 to fine-tune one of these.
Edit: Though I do agree that once this kind of filtering is in place during training, NSFW models will begin to pop up all over the place.
As it is right now, stable diffusion can generate adult imagery by itself, however it seems like it's been fine-tuned after the fact to try to 'cover up' that fact as much as they could before releasing the model publicly.
As far as textual inversion, JoePenna’s Dreambooth [2] implementation uses Textual Inversion.

It works super well for putting yourself in the images, the likeness is fantastic.
It’s obviously a small training process, they only take 20 images, but it works.
