We give the top channels ranked by their in-Katz centrality for channels in the downstream and core clusters and ranked by their out-Katz centrality in the upstream clusters. We show the top 20 channels, sorted according to their Katz score, in communities linked to the UK and US far-right and the top 10 channels in other communities. Channels marked with an asterisk correspond to group chats while the other ones correspond to broadcast channels
