That'll only work for a little while longer (for future named big-public-release models, obviously the cat's out of the bag for the current version of stable diffusion), right up until the point where they incorporate the filter into the training process.

At which point, the end model users get to download will be incapable of producing anything that comes close to triggering the filter, and there will be no way to work around it short of training/fine-tuning your own model, which is prohibitively expensive for 'normal' people, even people with top-of-the-line graphics cards like a 4090.
