Yeah I forgot they funnel everything through OBS. If there's literally no other way to set up a call, these type of mistakes can be avoided by making an account specifically for collab calls. For an industry that takes the secrecy of their talent's real identity they do the bare minimum sometimes.
It really would be smarter to use Discord solely for public-facing interactions (collaboration stream calls, fan interactions in the Phase-Connect server etc.) and a separate program like Slack etc. for private interactions. That way you'd be able to enforce a simple "open Discord, close Slack" policy that would very quickly become second nature, rather than using Discord for everything and constantly having to worry which particular chat is open at any given moment.
I mean even Disney had "Anyone with a link" google docs that had their links leaked in that big leak a few weeks back. Options exist but people don't think to use them.
It happens everywhere because, regardless of available technical resources and company policies, human error and poor in-the-moment judgement is always going to be a factor. Should every employee be schizo-paranoid about how they handle confidential company materials? Sure. But is it possible to hire an entire team who are all above sending a coworker
just one file on a personal account, because they left their work laptop at the office and don't have the right login to hand at home? Not at all.
Streaming in particular is open to these vulnerabilities because using Discord for everything is standard practice, so it's not like there's any prompt to stop and think about their options in this one particular instance. It's also true that, regardless of how much training they receive, few people actually take privacy and security seriously until they see something happen - and today's sequence of events don't really have a precedent that I can think of. The biggest example we have of a Discord oopsie being an actual problem was the Rushia yab, and even then the takeaway was she was a retard for trying to clear her name through a drama channel rather than just taking the L.
As a comparison, a lot of people here come from the farms and as such have a sixth sense for covering our tracks online, since we've seen all the ways people can piece together information to create a profile on someone. Most normies do not have this sense which leaves them vulnerable; even the ones who are at least somewhat conscious of their safety and understand the fundamentals like not posting pictures of their family members or announcing when they're going on holiday aren't going to think of things like "if I post this photo of my Christmas decorations, people will comb through real estate websites and compare the placements of doors, light switches, and chimney stacks to find my address" - because they've never seen that happen with their own eyes. It's a similar kind of situation with yab-prevention, nobody's privy to every possible weak point.
