In it's current form, it's a super simple hack that may or may not be useful to anyone.

Theoretically, something along these lines could be used along with Tor to be able to have unlinkable posts on social websites. A bunch of work could be done client-side (aggregating content / conversations from different accounts, etc), but each individual request to the web service could be made from a different IP with a freshly generated account every time, so from the point of view of the operator of the web service or any other user on the web service, it's not possible to tell who posted what, and content is unlinkable.

(it's quite simple, but maybe someone might find it useful)

While I applaud your effort in creating such an extension, I find it trying to solve a problem that doesn't exist. The registration process on reddit is so simple it really doesn't take anytime to setup a throwaway account

Yep, I agree. It was basically a 1-hour hack to make something that's already pretty easy marginally easier.

It would be cool to make something like this work on a bunch of websites... and perhaps make it completely transparent to the user, automatically creating a new account every time something is submitted.

very useful, thank you.
