Checking external site (LJ) for updates?

Hey, I was wondering if it was possible to build a script that would check an external website (in this case LiveJournal) for updates and email the user when true.

 

Mostly, I'm just focusing on comment tracking, which is something you can pay to have done on LJ, but I'm hoping to sort of bypass that? Ideally, a user would give the script a link to a comment thread, and it would email them when a new comment is posted.

 

Is this even possible? I looked into curl a little, but I'm not sure if it's the right place.

 

Any advice appreciated!

I suppose if you can CURL the page into a php variable, you can check the length/contents and compare with previous version to decide if there have been updates or not.

 

Sounds illegal though. If they have a paid service providing exactly what you want, chances are they'll detect what you're doing and block your IP, or even begin legal action against you for trying to explore their business.
