IRC chat would be my guess. Since data isn't stored on a server/can't be taken down, this seems like this could be useful in the shadier IRC rooms sharing questionable content.

If you're pasting the link, you may as well just paste the text.

The link is really just an encoded form of the text anyway.

EDIT: Not to shit on this project, it's just that pastebin's are typically used to reduce the amount of text that gets pasted in an IRC channel.

They're probably working on an (small) image 'host' using this same idea.
