They rely on user reporting. This is for EasyList, for example: https://forums.lanik.us/viewforum.php?f=62
Of course, the maintainers use the web too and find stuff to it by themselves, often.

On the issue comment you can see maintainers @-ing each other to add things to upstream lists, so it’s all one big community rather than being extension specific.
