> Non-elected representatives from my country keep pushing for chat control via the council. How do I, as a citizen, hold them accountable?

How is that an EU problem? Without the EU, like here in the UK, we had non-elected lobbyists pressuring our elected government to implement age checks, message scanning, etc. And it is still continuing.

You're fighting the wrong fight by blaming the EU for this.

Ask your government why they're sending those representatives. As a citizen you vote for your government, right?

It isn't popular, but they have a name and address right? Not talking violence, but the number one way of dealing with these sorts is to usually talk things out. If you're really concerned about, get a group of similarly minded people and make it unambiguously evident that this person is championing something a lot of people are not behind. It becomes much harder to ignore or wave off something when people start making themselves known on your doorstep.

And no, this isn't dog whistling violence. It is simply applying signal. The only other message I can think of is engaging an investigative journalist/PI and starting to figure out who is lobbying the person, and start pressuring them.

The article you're commenting on is reporting how directly elected representatives defeated the motion.

Why do you keep lying?
