User blog comment:Brandon Rhea/New Community Central Chat Guidelines Announced/@comment-31162206-20170505070900/@comment-26402117-20170505111225

I suspect the old rules led to users drifting around topics until they had stumbled into disruptive behaviour. Then you get this cycle of constant warnings and punishments. The guidelines limit chat to having guided conversation, where people can discuss a topic related to Fandom or a wiki but are not likely to canoodle or roleplay.

The conversations on Wednesday evening American time were drifting around many things unrelated to Fandom, most of the users and sometimes outside the guidelines for a couple hours (a bit of violent roleplay). But in general, none of them had a defined topic. That isn't really a good impression for anyone new to the chat, who may be looking for a helping hand or a universally nice conversation.

To conclude, if the rule change made CCC entirely unwelcome for you instead of clarifying, then you may have misunderstood the chat's original intention.
