I played around with them a bit. If someone trolls you, or sends you an unfavorable message, you can simply delete it. With some coding, we can easily remove the messages from Recent Activity. As for signatures, they're fun to have, but really, they're not an essential. Customization is fun, but would you rather have others able to edit your talk page, or have message walls? This is not Facebook, but this makes it a lot harder for spammers and trolls to undo your deletion.
