Very little information on the site -- how does this work? Presumably by storing the contents of every Reddit comment made since Decomment's creation and serving them up on demand? I imagine once you delete a comment on Reddit it's no longer available via the API or by scraping the site, but I was hoping something more interesting was going on than just storing comments in a separate database before they are deleted.
Reddit comments are owned by their owners, no (at least, that's how copyright works in the USA)?
How do undelete sites fly under the radar? Is it just that no one has been effected enough yet to warrant the hammer? It appears decomment.com is hosted on OVH servers in the EU (France possibly?). Aren't they keen on their "right to be forgotten" law?
A small number of reposts is ok if an article hasn't had significant attention yet. Otherwise too many good stories languish unnoticed on the /newest page.
It has a bookmarklet and activating on any Reddit thread will load the deleted/removed comments.
