In today’s strip, I think Marigold is being overly paranoid in step 2: Faye says something, and a nut-job fan overhears.
200,000 subscribers may sound like a lot, but it’s a drop in the ocean compared to the general population. Even if all her subscribers are in North America, this means only one in 2900 people is a subscriber, and most of those aren’t nut jobs. Even if we assume 1 in 10 would do what she fears, the odds are still really, really overwhelming that no one like that will ever set foot in Faye’s shop.
The rest of the cascade is plausible, but the reality is that letting her friends know she’s a popular streamer will never have any repercussions. The greater harm is that she’s lying to her friends, and that’s potentially dangerous to her friendships.
