Maybe requiring credit card payment would filter out LLMs. Is this gonna lead to closed-off paid websites ?
First, it would introduce a commercial aspect to my websites that I don't want them to have (too much of the web is commercial as it is).
Second, it would require me to have some sort of merchant account just to have a website. I don't want that additional hassle.
In the end, it doesn't appear to be a better solution than to just make my websites invite-only.
