Oh, I had no idea they started adding domains like blogspot.com--that's clever! They must have just started doing that recently. And not quite as much of a hack as you say, really, since the justification is the same as the other suffixes.

[_delirium]

The justification is the same, but it seems much less feasible to be "complete". There are a pretty manageable number of TLDs, and they generally have published policies about what they'll publicly register, so you can plausibly collect a complete list of which suffixes are public ones. But covering stuff like blogspot.com has to be done on a case-by-case basis and will be wildly incomplete. It mitigates the problem by including some of the higher-profile sites, but it doesn't seem like it can solve it generally.
