There are currently 3 domains available. If this takes off I could do something like mailinator (offer the user a small selection, but never reveal the full list at once).
You can also register your own domain and point it at my server and your canary will work just fine on that domain.
If you're playing at a high enough level that you've specifically blackholed URL Canary traffic by IP address, then you're a worthy adversary. And additionally, that is a splendid problem for my project to have.
On the enterprise tier you even get your own server with its own IP address, so there should be nothing linking it to URL Canary at all. (Although the enterprise tier is extremely expensive, and if anyone buys it I will probably panic).
