IP based limitations are a terrible idea. Multiple users can be and
often are behind the same IP if they're in some sort of intranet, be
it corporate, academic, or simply multiple home computers. Mail-based
authentication can be screwed with, sure, but it's also very easy to
notice this (as opposed to ip nonsense) through simply eyeballing the
results. There's no general everywhere way to prevent vote fraud.
However, if we make it even require a mild bit of thought, that
should be sufficient in this case, as there won't be enough votes to
prevent some sort of rough eyeball-based check of the results, and if
there are, then that's a sign of fraud for sure! Furthermore, there's
very little incentive for someone to go the extra mile here, as we're
voting for a haskell logo, and not, e.g., giving away ten thousand
dollars. Furthermore, since I assume we'll only be presenting
reasonable logos, there's not even some room for pranksters to stage
a "write-in" of some gag slogan.
Cheers,
Sterl.

We should limit voting, and limit based on IP. If we go via email,
then anyone wishing extra votes merely needs to use mailinator.com
(and its dozens of alternate domain names, to say nothing of
competitors providing similar services) to vote as many times as
they
want. If we care about fraud, then it would be a very troublesome
task
to filter out all those ways to fraudulently vote; if we don't care
about fraud, then email confirms are just a burden on honest users.
I don't know about other people, but for me it takes less time to
change IP addresses than to sign up for a mail account.
dhclient -r dsl0 && dhclient dsl0
vs. fill in a form on a webpage.

You don't sign up for a Mailinator account. That's the whole point.
