You mean, people who operate a platform where people's privacy constantly gets violated should have a right to their own privacy?

I dunno. I understand your point, but @Telorand@reddthat.com is also kind of right.

lots of rights get modified, curtailed, or eliminated by the larger society based on misuse or misbehavior or other transgressions.

(or positions of power, etc...)

"Live and let live" obviously doesn't work. 4chan has done so much damage to the world that I wouldn't mind seeing their big players in gallows in the town square.

All rights are privileges, if we're going to be pedantic. This is evidenced by the fact that they can be taken away. Society tends to operate on an unspoken, collective agreement that certain rights should never be violated, but if they were actually intrinsic, we wouldn't have to fight tooth and nail for them.

I'm a moral relativist, so if someone is happy to abuse their right to privacy to harm others or otherwise take their rights away, especially the right to privacy, I don't feel any compunction to draw a hard line and say that the harmful person deserves to keep those rights in spite of their actions.

I'd say it's more like a right that's been taken away and they're okay with that.

If you're breaking the law then you forfeit your rights in favor of some much more restrictive ones.

Do you believe liberty is a right? It's one of the first laid out in the Universal Declaration of Human Rights, and yet I don't think a single signatory nation doesn't incarcerate people guilty of crime. By your logic, I don't think there are any true "rights" in existence, because there are circumstance in which any of them can be taken away.
