Let me just be frank. I really don't see the purpose of most DNIs. Unlike a TOS, where there is an explicit legal definition of who a site allows on it, which can then be used to justify (usually honor-based) hurdles, like a box that asks "Are you under 18?", DNI lists are usually far vaguer.

It's always good to have warnings where necessary, but do you really need to have every hypothetical punitive trangression listed out?

If someone wants to view your site, will being on a DNI list stop them? I wouldn't bet on it.

In cases where there is a significant chance that your content will be used in a way you disapprove with, then yes - putting a notice does make sense.

Let's take as an example the hypothetical Countess Donelli (1924) fandom mentioned on the left. This is a lost film from 100 years ago which has mostly been forgotten, so this shouldn't hit too close to any real fandoms someone might be in.

If I were producing Mathilde fan content, and people who ship her with Graf Bergheim make me uncomfortable, then yes, it would make sense to say something like "Please don't use for Mathildeheim content!", on warning of a block.

Do I need to also say "Don't interact if you are in the Wizard of Oz fandom" though? Probably not.

Interestingly, this idea of "prevention over being punitive" is actually Wikipedia's policy as well.

So I say this, why don't we move a step back, take a deep breath, and only warn when necessary? We can all enjoy our own Mathildeheims without needing to read and write our own personal codes of conduct.

I do have a page about who I would be interested in interacting with this site though! (WIP) Why not take a look? :3
