It doesn't work that way.
You'll only get points for having locked threads if it comes to a point where it's just spam.
If the threads keep getting locked because they are duplicates of other threads, then try using the search bar.
Repeated dupes will probably get you a warning, keep doing it and you'll get points.
If it's because you created a legit thread, and people are just being knobs and it gets shut down because of that, then that's not your fault and you won't get points for it.
