I would like to propose a solution about these newbies that don't do anything than damaging and spamming the forum. Once a newbie creates a new topic, the moderation team must approve it first. I wouldn't suggest posts generally because there may be some honest newbies that face an issue. Just for their topics.
This is simply not scalable because as the forum grows, there will be more posts by newbies, and newer users. It will also mean that someone wanting to get around this restriction will simply make a handful of posts over a few weeks, including one good enough to receive one merit to rank up before opening a topic. Or a scammer could hack an account to create a thread.
Currently, there is the
patrol that brings attention to posts by newbies, and there is a large subset of moderators that have the ability to moderate threads by newbies. If not already implemented, reports against newbies should be given priority in the moderator queues.
