Threads have always been moved when appropriate, especially in the ask a question forum. But it was done by admins when they found them. By giving us an easy way to report them then it makes it easier for the admins to find and get them moved. As far as finding the thread, you will still receive a notice when someone make a post in that thread. If you are looking to return to a thread that you started you can go to your profile page and click on View posts made by (your screen name) then click on View the threads started by (your screen name).
