That’s the one I know. There’s also XMPP if you can use something less feature rich.

I use Adguard for this purpose. You need a license to access some features. But, it can block ads even on sites which directly serve ads

Thanks for the heads up. This will make sure we never commit such criminal activity ever again.

Your whole existence revolves around peddling ads before people can watch the ads they want.

Ah, what. Who wants or likes to watch ads at all?

Where did they say that?

You have to add a custom addons collection. That’s how.
