What's up with cluster of users like:

j_s,password4321,carolinew,colinwright,kuharich etc.

https://stylometry.net/user?username=j_s https://stylometry.net/user?username=carolinew https://stylometry.net/user?username=colinwright https://stylometry.net/user?username=password4321

Lowest match for j_s is 0.80 and all but one is black.

On a cursory glance it looks like a cluster of users that post links, especially with italicized quoted excerpts.
