I look at posts here and on all forums that support it by using the "new posts" (unread content) button, so I don't see them in the (sub)forum index. I haven't been paying attention to which subforums might have issues. If the tables for one subforum have corrupted tables then it might depend on how you have to traverse the tables to get there that would expose it more for some than others.

In the days of big databases there were utilities that could walk all the links and look for inconsistencies. I don't know about the database engine used for forums but I'd be surprised if there wasn't some kind of integrity tool.
