Contrary to the other ideas I'm going with reverse psychology being the reason as I like to come up with the wildcards from outside the box. It's there as a code to signal others what the user is into rather than against.

Sort of like how DrPizza got arrested for attempting to solicit sex with a child despite all the claims that 'pizza' as a euphemism was just a meme.

Or it's just more blatant virtue signalling trying to gaslight others. "See, I said I was against the thing! How could I like the thing if I said I was against it?"
