I used to be heavily against closing inactive forums. I believe if they're just discussion posts (and not something technical like "how to prevents JS from breaking this button") they should be locked if the conversation is concluded and only spam bots are targeting the post. If I notice a pattern, like how described above, I believe removal and ban is necessary. It's very possible these bots are scouting out inactive communities by posting non-spam comments first!
