If you just want to mess with naïve opportunistic scrapers Nightshade-style, you can

1. apply a substitution cipher to your text

2. apply the same substitution cipher to a font file

3. display your text with the modified font

This will annoy scrapers, blind people, people who disable web fonts, people who use automatic translation and copy-pasters, etc.

If you really only want to make AI training more difficult, then you're asking for the impossible and nightshade doesn't deliver on that promise either.
