I think the most important things to keep an account safe are consistency and natural activity. It is important to log in from the same IP address and the same device to keep the account safe. In my opinion, it is not enough to just be active every day, but also to naturally view posts, comment on relevant posts and interact with others. It is also important to avoid unnecessary activity and repetitive tasks. The most important thing is to use the account naturally and follow the community rules, then your account will remain stable for a long time.
