Topics in offtopic can be helpful but very scarce to see them. No value topics in offtopic can a topic for spammers. I don't know moderators accept reports to lock those topics if I submit my reports. If a topic is no value at birth and after a while, is it good to lock it forever?
Submit your reports and see if moderators would act on it. Of topic board is a board just like others and shouldn't have a lower criteria in terms of moderation, so if a post is low value and contributes nothing it should be deleted or thrashed by the mods regardless of where it is posted. It may be more difficult to tag a post as low value there as the board has a broad spectrum and isn't about any particular subject, but obvious spamming should not be tolerated.
