Yes, everyone should practice OPSEC, but a public "celebrity" who's sole business is online doubly so.
She doesn't practice OPSEC because she has an OF that exists? I am not nearly as aware of her OF as the people that don't like her, so you'll have to let me know if there's something different she should be doing with it.
to determine whether friendly actions can be observed by enemy intelligence
I must be really out of the loop. What is her business that results in her having enemy intelligence? Is it being on OF that gets you enemy intelligence, or making comics?
Sure. But that sounds like her problem, not a reason for me to dislike her.
This sounds a lot like "there are duchbags attacking her because they are misogynists" which again, is not a good reason for other people to dislike her.
