The major thing I can think of about cheap throw away accounts is well... throw away accounts, for answering or commenting or asking questions on/about matters you'd rather not have your IRL friends see or whatever.
It's still possible to make a new account to answer questions that you may not want IRL people to see - it's just that that new account won't have the ability to go causing a lot of problems elsewhere on the site, via the downvote limit and so on. Snapzu's methods are hardly restrictive, but they are designed to encourage people to invest their time into being a good user.
