Community statistics and their top users in the signed network (with size>100). The average issue sentiment is calculated over the sentiment (pro-Black Pete = 1, anti-Black Pete = -1) of all users, and reported separately for the top 10 users most often positively related to from within the community. Column ’pos int e fraction’ divides the positive edges within the community by the total positive edges outgoing from community members and ’neg out e fr.’ divides negative edges within the community by the total negative edges outgoing from community members. The columns ’avg pos int e’ and ’density (pos)’ divide the total positive edges by the number of users and the possible edges in the community, respectively. The column ’top global negative’ lists the users in this community that are most frequently negatively mentioned by other communities.
