I'm generally against the idea of banning subreddits because they just move elsewhere. However, if this is going to be the official stance of Reddit admins, I encourage them to take a look at /r/sino and a few other communities that regularly violate the rules.
Deplatforming works. A few people follow to other sites, but most don't. It also becomes harder to attract new cultists if one is shut out of major services.

Wow, that sucks. What ISP is that? Why can't they just take the money and host the service without censoring other people?
