Table 3 Mixing matrix E of the edges between the types of accounts. We characterize the type of an account by the sign of its media PCA score

As usual, ‘Left’ indicates a negative media PCA score, and ‘Right’ indicates a positive media PCA score. (No nodes have a media PCA score of exactly 0.) Accounts tend to mix with (specifically, be adjacent to) accounts with a media PCA score of the same sign, as indicated by the larger values on the diagonal of the mixing matrix.
