That is why I made a suggestion.Then you would not be able to see any announcements that are also locked intentionally.
...and everyone can see that threads, violating the rules, will actually be locked.
That will hopefully make flame war starters, rethink their plans and not start such a thread.
I think that worked quite well in the past.
Talking about "unanswerd", there is a filter already. Though, it's the other way around, as it does not filter those threads out, but only shows the unanswerd threads.
