yeah, that's why i say the old IRC model is the best, because you can set very fine grained policy on retention and access control and even things like users being able to block sending events to users they don't want to see it specifically, or whitelist where you make a set difference of their whitelist versus their blocklist and the chanserv will only deliver events according to the author's preferences

i have been thinking about these subjects for a long time since i started using IRC in 2003
