FAQ - Emoji Steganography

Q: Can these secret messages expire?

A: No. As long as those Unicode characters are not stripped or modified by intermediary platforms, the message will remain forever.

Q: Why does the number of emojis increase?

A: The storage capacity for secret messages depends on the number of "cover emojis". The longer your message, you might need to use more than one emoji to house the data.
