Managing multiple MP accounts safely requires each account to run in an independent environment - using a residential proxy or mobile 4G is optimal. Absolutely avoid sharing IP, device or browser because it is easy to get the link marked and the whole group will be taken away. With new accounts, you should warm up for a few days, increase trust and then start posting. When posting, you need to change the title, description and photo to avoid duplication, and divide the posting schedule evenly throughout the day, do not spam all at once. The important thing is to control behavior to be like a real person - natural operations, regular interactions, and do not scale too quickly.
