What is a water army? What's the difference between Tong Ming Media Xiao V and the Water Army?

My personal understanding of the water army is a bit like a keyboard man, except that the water army is hired. Tong Ming media Xiao V is actually a bit like the amateur powder mentioned by Xiaohongshu and Weibo Platform. They are real users and have the ability to organize their own language, while the navy is generally edited in advance by a team of copywriters, with a stronger purpose.
