Definitely worth it. It pushes actual worthy discussion down the page, and it will then be forgotten in an hour, and never return. You see this all the time. I appreciate it from the standpoint of a user of the forum, and I'm sure a lot of other moderators do too. Unfortunately, I only remove topics when there's not many replies, and they are pointless. Otherwise, I'll lock them, but if they are out of my jurisdiction I'll ignore the report, and allow another moderator with permission to lock it to deal with it.

I'd rather get to the point where we are removing these trash threads than simply just locking them. It's better to do that when they don't have any replies, and before they become a problem. There's several threads asking the exact same question or generic statement. I'm pretty sure they look down the page, and take inspiration from previous threads, and can't think of their own content so just use already existing content.
