I'm not supporting this, just trying to explain why not actually posting porn is no workaound to satisfy the ads company.
They are being banned for who they are, even if the decision is being delegated by Instagram to angry members of the public.
For instance, the article mentions Cinderella Jewels, which has a new account showcasing her "pole journey". NSFW: https://www.instagram.com/p/B4xM_b4AtC-/ and her Youtube banner: https://yt3.ggpht.com/L6jM6xMK_QBRZieP8x8f8_f6x1BYQi30_K7WGL...
Here is Bloggeronpole showing "body positivity", while complaining they won't let her post a video of her working out in a bikini NSFW: https://www.instagram.com/p/B2td-HPgzDP/
Here is Ginger Banks' instagram, who claimed in the article: "I've never posted explicit images on Instagram. But even a picture of me wearing leggings could be extremely provocative to someone, and worthy of being reported": NSFW: https://www.instagram.com/thegingerbanks/ and here you can support her art, for just 100$ a month you can help end the stigma that is surrounding sex and view art that makes you question yourself: https://www.patreon.com/GingerBanks (NSFW).
Once the wealthy and powerful know everything there is to know about you, they can take any arbitrary decisions they want against you - in all places, online or offline. They can effectively "ban you from society" just because you did something they may not like.
Worse yet, that "something" may be decided by an "AI" they created and there will be no recourse (people dealing with Google/Facebook "support" probably know what that means).
