@PitaJ is correct, the option is called the "tags whitelist", and you can decide which tags to allow, and do so on a per-category basis
Nodebb partitioning code
I'll work in my research with 'late distribution'. This is a term adopted by me rs. It means that I need to split the code to work in multiple clouds. For example, the 'module' topics would be deployed in Amazon EC2 to use the load balance and the rest of nodebb code in GAE, implementing some communication between the code on the EC2 and GAE. Some ideas?
