You may or may not find this easier, but I found out how to actually delete threads rather than just "removing" them.

From the contributions page, you can click on the post's revision rather than the thread's page, then change the end of the URL from ?oldid=XXXXX to ?action=delete. After that, just hit Enter twice — once for the URL, then again to confirm the delete.

This method deletes the thread for real rather than just hiding them and it doesn't make you follow the page. Hope this helps.
