paul's blog article on smuggling arbitrary data through an emoji

"To be clear, this is an abuse of unicode and you shouldn’t do it. If your mind is wandering to practical use cases for this, shut it down. That said, I can think of a couple of nefarious ways this could be (ab)used:

1. Sneaking data past human content filters

...

2. Watermarking text"

Lol. I consider the whole emoji spec an abuse.

doesn't mean emoji's are dead

more that Paul's tool is simple by design and we have taken it to send ecash around

upcoming peanut emoji NIPs are far more interesting IMHO, but why not have convos via emojis?

reminds me... have any of you watched Pantheon? First few minutes of the first episode you have an emoji convo.

truly mind bending...

Are you working on the cashu emoji spec? Let me know if the encoding changes, I can adjust on Amethyst.

not me, just excited about it
