The ban seems like it backfired to me. The article brings up LSA briefly, but there was a sort of broader almost class division where there terfs have more of a home on sites where there are a lot of working class cis women and racial minorities now.
LSA is the best example of this because it is a lot of people who would get kicked off twitter where the celebrities are, but the site's fame came from it having a lot of women posters who are basically the working class of Hollywood and had a bunch of insider gossip about different celebrities. So the dynamic of terf stuff being a bunch of bougie white people talking to other bougie white people on reddit is gone and when class bleeds through into LSA's other discussions it's basically the Chappelle bit where trans issues are framed as bougie issues, a bougie plot or some element of white supremacy.
