Do they get some kind of real-time feed that tells them "hey this URL popped up in the web today, but it is a tracker, so block it", or is this exercise is mostly helped by the crowd ?

I love regex, I'm not even gonna lie. To be fair, my expressions haven't been 50+ characters long, but still.

    Regex absolutely has many great uses. The issue is people trying to use for things they shouldn't. Then it suddenly becomes a nightmare.

    Can I parse [X]HTML with regex?

    You can parse any plaintext with regex, but I would recommend using XPath for that use case, instead.
