@Frankenbeans This is every discussion about trolls in USENET ever, 30 years ago. Welcome to a decentralized, autonomous server operator world. It's like this, by design - unbannable people, people getting more accounts, people that annoy you. The only thing that works is filtering at the reader end, killfiling, collaborative killfiling. Everything else - nope. Getting people off the network - nope, especially when they operate their own servers or networks.
