There is a lot of demand for digital privacy and security advice out there right now and lots of people are giving advice and writing guides. I beg them to do a few things:

1. Be explicit about the threat model your advice is meant for.

A meme that says to close ones tab, is to admit you were never truly committed to the journey. there's a costume fox that's faded in the background with a person in the center meditating. in focus is an image of a browser tab with a prompt that says close tab. it looks like a cheesy motivational poster from the 80s and 90s.

They don't seem to appreciate the humor of an email address that is also a shell command injection attempt or the time zone of -2456.

Also, Bsky is painfully US-centric. Most of the posts talk about US politics and its drama. I think it's an important topic, but it looks like it's the only thing going on over here.

Maybe it's just my discover tho

PSA: If you choose to submit a novel research talk to one of the top security conferences in the world, maybe check your proposal text all the way through so "Claude may make mistakes. Please check your answers." isn't the final line.
