The evidence provided above is merely a sample and represents only a tiny portion of the overall evidence.
Through thousands, if not tens of thousands, of spam posts, the same content and files have been repeatedly circulated, showing the scale of this coordinated effort to manipulate public opinion. This activity highlights the need for further investigation to fully understand the extent of these actions.
The graph above visualizes the estimated distribution of approximately 1.5 million total posts over the past two years, categorized as follows:
- Macro Posts: Estimated between 100,000 to 200,000 macro posts, with both the lower and upper bounds displayed.
- Manipulation Posts: Approximately 800,000 manipulation posts, excluding macro posts.
- Deleted Posts: About 24% of all posts, estimated at 360,000.
- Remaining Posts: Estimated at 640,000 posts, assumed to be created by regular users.
- Total Posts: A total of approximately 1.5 million posts.
This structure provides a clear breakdown of the ratio between manipulation, user-generated content, deleted posts, and the overall post count.
