To create a BM without getting limited, the most important thing is to start from a clean soul, have natural interactions and log in stably on a clean IP. When creating a BM, don't do it in a rush - after creating it, wait a few hours or a day before continuing to add cards and create an ads account. Avoid fake info too much, don't create many BMs in a short period of time, and limit logging in through many different devices or IPs. Each step should be done slowly, similar to real user behavior, the more natural it is, the less likely it is to be scrutinized.
