Erasure-coded comments distributed across the huge number of abandoned Wordpress blogs and phpBB forums that are out there. Plenty of storage, pretty readily accessible, low probability that even one fragment will get deleted, and even if one does that's what the erasure coding is for.

EDIT: also, Wikipedia never deletes anything. Even if your "edits" get reverted, you can still find them via the history page. Hmmm.

no, deleted media is gone forever IIRC.

deleted pages are not visible to people with less than sysop rights (on enwp), and multiple methods are always available to deal with troublesome people, ranging from revision deletion to blocks and eventually ISP contact.

Wikipedia is a bit more vigilant with banning than abandoned blogs are :)

A single user storing a reasonable amount of data though might get away with it... I know what I'm doing this weekend.

Abusing one of the most important, non-profit resources on the internet?

Just because we can doesn't mean we ought to.
