This reads kind of like an advertisement. Plus it's subtly wrong.

My experience with the NameBlock API is that for those $99/year, they'll allow you to automate purchasing all similar domains. But then you have to pay registration fees on all of those domains, too. It's only $10/month per typo domain that you buy, but it sums up really quickly.

You're thinking of some other service, not NameBlock or GlobalBlock. There's no automated purchasing of all similar domain names. You don't pay registration fees, as the domains that end up being blocked will never be registered by anyone (not even you).

There literally is a block on the variations, it works at the Registry level not the registrar level.
