IP address rental

I've been getting mail from "" offering to rent unused
IPv4/IPv6 space. Their web site is a farce of random phrases,
grammatical errors, misspellings, and randomly inserted words, and won't
even render in Firefox.

You need a larger warning may be dodgy sign?

Also, is there some reason that there is no official searchable archive
of the nanog mailing list? (or dependable unofficial one...)?
