If we were to do it for the entire forum, you would get all of the new malware topics, which you are not allowed to reply to, as well as all the other forums you might not be interested in - off-topic, development, etc. Since you seem to have a few areas of expertise that you visit frequently, isn't it easier to just check those forums?
Very much true in my case, but I was talking in a more general sense. I understand it could be a hassle to implement and it's not really mandatory to have, just a suggestion.
The waiting room serves a similar function as I had in mind (catching the topics with 0 replies), but it requires user action. It is enough though to catch the topics that really need attention.
