Can you go into a little more detail or provide a pseudo example?

I'm confused at how this allows spammers to self-identity.

If they strip it out you know the want to spam you so can block their domain and/or decline to sign up.

And if they don't strip it, you can add a unique identifier to your address for every site you use it on, and know who sold your address.
