I mean, if you could call it content, yeah. The photoshoot with the plushies that she released first on fansly. Only 5% spicy with nothing showing in full cosplay. I think she was testing the waters and was surprised by the results. Not just the positive feedback by fans, but the near-immediate leak and thirsting might have turned her away.
Yes, I have no doubts that Sinder is aware of internet leak culture. I just think she didn't know how crazy it gets. MAYBE in a year or two we'll get IRL cosplay content, but I won't expect IRL spicy content for the same reasons as the previous poster- it sticks to her and not her persona.
