I haven’t actually been in that chat room for any reason, so I haven’t seen any of the writings expressed there, but I’m interested in the question (paraphrased) “does there even need to be an off-topic place for posts? Does Blizzard find the need to have such a place for off-topic posts?”
The “Off-Topic” has a long history in online communities, and I think the reason this happens is that when any group of people get to know each other in one context, the desire to talk about other things naturally erupts.
The “on-topic” discussion is what may originally attract people, and depending on the goal of the organization off-topic may be desirable or not. If the goal of the organization is to be purely a resource or representative, then off-topic doesn’t make a lot of sense. If the goal is to create a community of people who become friendly associates, then off-topic is a way to maintain organizational focus while providing a space for socialilzing about other matters. I see Strats as being the kind of place that is fostering community, so providing means for people to interact in multiple ways about multiple facets of their lives seem within that. So “off-topic” conversation is really part of the overall organization goal. It’s “off topic” only in the sense that it’s not about gaming.
If there are terms of service violations like hate speech, personal attacks, an so on going on, that would definitely be grounds for some kind of suspension I’d think, but probably on the person level. As a “mature” gaming organization, maybe what’s not so clear to people is what “maturity” means? If there is a lot of silly shitposting in the channel, I could see that as being grounds for removal, but if its not clear in the org guidelines what counts of “mature”, then it’s debateable either way.
