Apologies for this question - I've tried to search the forums & web for it, but given the subject, I get bogged down in errata.. :/
So, I have a forum, and I get a lot of spam. I delete the spam posts, but it leaves with stub pages that say simply "Topic not found. Back to <My Forum>."
How do I get rid of these stub pages? It's making Google complain about having too many 'soft 404s' which I can't really argue with.
Is there a way to:
a) delete those pages, and
2) stop them appearing in the first place?
