I hate to have to state the obvious but I will anyway, there is just no possible way to blanket cover the room on a 24/7 basis, there is always going to be gaps in the coverage and issues that arise from those gaps.
That is one reason there is an ignore button. And think about this, if you screenshot all the overage or rule-breaking activity and send that to any moderator or me they can be dealt with even after the offense has already taken place, so that would be my suggestion.
