Let me say, though, that I absolutely respect your privacy and have no intention of looking at your data. It's as private as you want it to be. I'm also happy to put this in the TOS.
Exporting is another story as its easier said than done. Emailing you the pastes periodically (optionally), however, may alleviate that problem.
OP's issue wasn't so much privacy as it was permanency, as I read it. So using Gmail, I can rest assured that in five year's time my documents will still be around, just as they are today. Whereas with a new service, who's to say what lies in store for it? What if you pivot? What if you're acquired? Unfortunately a service like Gmail wins in this context.
What ever happened to 'your own hard drive'? Is there some reason people can't use that for storage? I have a VPS that I use as a file intermediary. I'm highly confident that, and my backups, will be there in 5 years.
This is the miracle of web hosted software for most users. It's also what makes Dropbox so special.
Of course, a burned DVD isn't going to let me access my file from the office and at home unless I take it with me, so there are drawbacks.
IMO, Dropbox and similar services are the first real viable replacement for e-mailing files to yourself.
So, I, for one, don't exactly care about what happened in your tin-foil crazy edge case.
But the gist of what I was trying to convey is:
It's 2011. The web is inherently tied with javascript.
(The "progressive enhancement" thing in respect to lack of javascript doesn't hold after Ajax and the so-called "Web 2.0", ie since 2005).
Turning js off AND using a left-field browser, is probably pushing it too far, and you don't really get to complain about broken functionality after that.
Opera is a great browser and has good support for HTML5 and CSS3. In fact, since I refuse to live without snappy Mouse Gestures, I don't even really have a choice in my primary browser.
Also, redirecting a browser somewhere without using JavaScript (since it was disabled) should be a reasonably simple operation.
And finally.. Tinfoil? All in all, there was absolutely no reason for that personal attack of yours. So yeah, try to behave.
What's the supposed benefit of breaking 80% of the modern web?
Using lower resources?
Sites not "tracking" you with cookies?
Better security?
