When I was a newbie the first thing I did was to read the rules. People fail to do that as they do also to terms and conditions. No body reads that. We should have the habit to always read rules and regulations and also terms and conditions. Laziness is not encouraged here. Let's me guided newbies.
In fact, this is not enough because nobody will remember every rule after reading. Bitcointalk forum isn't similar to any other social platform because of the complexity of its systems. The trust system is a unique mechanism to ensure the decentralized power among the community members without giving the permission to admins to control it, while in other forums, admins control the trust ratings. The merit points also in no difference with karma system but with the difference it cannot be traded or begged for. A lot of other complexities that only spending time navigating the forum is the only way to understand and adopt it.
You can spend time navigating the system and make too many mistakes that will get your account banned. You still have to read through the rules. As you stated that it is not enough just to read and remember all the rules. But it is very important. It will definitely save you from many troubles in the future. As too much mistakes will be treated as spam or something else by the moderators.
