Oh no, not Andy Ngo and Project Veritas!

No sympathy for fascists.

This is a good idea but, frustratingly, a lot of registration forms reject the "+" as an invalid character in an email address despite its being part of the spec. However, if one controlled one's own mail server it would be trivial to combine the grandparent poster's scheme and your own by adding '.' as an extension-delimiting character, with the added benefit that it would be more difficult for spammers to detect.

I've been doing just that with postfix for a number of years with great success.

This won't accomplish what you intend - the .onion addresses are looked up within Tor, bypassing your standard DNS infrastructure.

Fertilizer, irrigation and pesticides all depend heavily on fossil fuels.

And then there's this, from the wikipedia entry (yeah, yeah):

Back to your post:

You've struck upon the crux of the issue: there isn't another possible source that's even nearly as energy-dense as petroleum, and that's a problem. Also, the current agricultural system is deeply entrenched in its oil-based infrastructure. Transitioning to another - albeit much less energy-dense - source will take incredible amounts of time and energy itself, and will have marked effects on food yield when it does happen. And by the way, people are already rioting over the current food prices.

Not only that, but "OEM and the Craplets" may be the best band name I've heard in a while.
