I’m wanting to remove my user from the about page of some sites I manage. I’m not the one who’s going to delete your account, or anything else. . .
One way is this:
> [@How to hide admins from /about page](https://meta.discourse.org/t/how-to-hide-admins-from-about-page/43678/2):
>
> Since we often have to be admin to diagnose issues or change settings on our customer’s Discourse, we decided to hide all our @discourse.org accounts from the admins lists. That way, we’re not polluting our customer’s admins lists. We do this using a plugin that is automatically installed to all the Discourse we host and does something like after\_initialize do add\_to\_serializer(:about, :admins) do object.admins.reject { |u| u.email =~ /@discourse\.org/i } end end
But a plugin seems a bit heavy-handed these days, so I have a theme component that does this:
```plaintext
import { withPluginApi } from "discourse/lib/plugin-api";
const hidden_admins = settings.hidden_admins.split("|");
const PLUGIN_ID = "hide-admins";
export default {
name: "theme-javascript-initializer",
initialize() {
withPluginApi("0.8.30", (api) => {
api.onPageChange((url) => {
if (url != "/about") {
return;
}
for (const admin of hidden_admins) {
var element = document.querySelector(`[data-username=${admin}]`);
if (element === null) {
break;
}
element.classList.add("hide-me");
}
});
});
},
};
```
Is that stupid for some reason? Does that onPageChange cost very much? The plugin would affect only the about serializer, this does a check on every page change. Is that bad?
There was a topic about just this issue lately that just hard-coded the user in the CSS. Would having just a single CSS in a theme that just did:
```plaintext
.about-page div[data-username="pfaffman"] {
display: none !important;
}
```
be better? It wouldn’t be useful for anyone other than me, which is why I sort of like this theme component idea.

So for every page turn except “about” you are processing ~two lines of extra javascript?
No I don’t think that is bad given the enormous amount of javascript that runs all the time on Discourse 🙂

That’s mostly what I thought, but I very much appreciate your confirmation. I’ll see about prettying this thing up a bit and making it public and then writing tooling to automate adding it to some sites.
Thanks very much.

So Jay would this be a plugin to install or a Theme-component?
I think this could be handy to even extend functionality to even Mods. For some use cases.

This is a theme component. I’m still cleaning it up a bit. I’ll make a proper theme page for it on the next while, but you can see [GitHub - literatecomputing/discourse-hide-admins-about: Theme component to hide some admin users from about page · GitHub](https://github.com/literatecomputing/discourse-hide-admins-about) if you’re excited to try it out.

That is quite cool. I am content though to wait for your official roll out.
