Are anarchists any good at opsec? Is there something particularly anarchist about opsec, or something particularly important about opsec for anarchists?
On the one hand, I've seen anarchists exercise paranoia about communicating with each other, even when discussing things that are entirely legal. On the other hand, the state asymmetrically monitors and pursues anarchist activity as criminal, even when it's not, and so any efforts at practicing good opsec seems better than being careless about it.
What are the most important guidelines, practices, pitfalls to avoid that you can offer about how to have good opsec? What are some ways that you see anarchists being overly paranoid about opsec? How do you think opsec practices differ regarding in-person activity and online activity? Is practicing good opsec online impossible, or is it more difficult than practicing good opsec in person?
