At least some of the signs were desgined by Anders Sandberg:

Important context: it's a mix of things that do and don't exist which all have a certain cachet with junk science. Tesla coils are definitely real, for example. It's just that junk/fringe science may use them to make their flimflam theory seem more exciting.

    I similarly thought this was supposed to be a list meant to help you identify when someone is deploying fringe science. But in the context of the community (sciencefiction) and some of the other comments, I've realized that I think it's meant to be sample signs you could use in a story like at a lab where that kind of "science" was being done.

    AFAIK all of them are fake warning signs but, as you said, some of them reference real stuff.

    I didn't add any indication that they are fake because I assumed it was implied by posting in science fiction communities. If not, I will add a warning.
