The Internet's Typographical and Grammatical Morass

I am stumped by how to excerpt the language on message boards and blogs.

Take a passage signed by zipthwung, an astute online commenter: "pornography if for the ruling classes and their violent vulgar all consuming appetites. Or their slaves."

Interesting. But so as not to distract you with the typos, should I have repunctuated it, adding commas and plunking a hyphen into "all-consuming"? Should I have turned that "if" to "is"?

Zipthwung — I can testify, as a longtime fan — is a poet and a mystic. Maybe he means "if." Dude thinks that way. Oh, but there's more. Before quoting him, should I have determined his real name? Gender? Profession? Home address?
