When the lease on your domain expires, it often gets snapped up by what are called “parking” outfits (which is like calling a toll booth a “roadside hospitality concept”). A parking domain is basically a dead address turned into a little money farm: no real content, just ads, redirects, tracking pixels, and a vague pretense of being a website, all optimized to squeeze value out of whatever stray visitors still wander in.
But what if the domain that falls into a parking company’s hands was not serving articles or blog posts or cat photos, but scripts. Say, for example, a CDN endpoint. Or a banner network. Or some forgotten third-party JavaScript that thousands of living, breathing sites still quietly load in the background.
Well then the fun starts.
Because now the parking company is sitting in the middle of someone else’s supply chain. They can redirect visitors from perfectly legitimate, still-active sites that happen to reference that old domain. And they do it in a way designed to stay invisible. No big splash. No obvious breakage. Just a slow siphoning of traffic that can go unnoticed for years.
For example, here is a case where traffic was stolen from EJ.ru for four years. Four. Nobody noticed until someone sent a bug report that basically said: “Why can’t I archive pages from EJ?” And the answer turned out to be: because somewhere in the stack, a script was loading from a dead domain that had been picked up by a parking company and turned into a redirect machine.

So when people start talking about hacker ethics, about bug bounties, about responsible disclosure, you start to wonder how that whole moral economy is supposed to function when the so called respectable domain investors are behaving a little worse than the hackers. Not breaking in, not exploiting zero days, just quietly sitting on expired infrastructure and milking the pipes that nobody remembered to shut off.
