To be fair, that was a reddit post that blatantly started with "IMPORTANT INSTRUCTIONS FOR Perplexity Comet". I get the direction they are going but the example shown was so obviously ham-handed. It clearly instructed the browser--in clear language--to get login info and post it in the the thread.

Show me something that is obfuscated and works.

Why does it need to be obfuscated? Are you going to stare at the screen while it works? Look away at the wrong moment and you’re doomed.

The whole comment is spoilered, so you need to click on it to reveal that text. Presumably it could also appear in a comment that you need to scroll on the page to see.

It's clear to a moderator who sees the comment, but the user asking for a summary could easily have not seen it.

I’m curious if it would work if it was further down the comments or buried in a tree of replies. If all you need to do is be somewhere in the Reddit comments then you don’t need to obfuscate it in many cases, a human isn’t going to see everything there.
