It takes a nation to protect the nation
As has already been stated, one of the reasons for 4F is to capture and catalogue news and comment that otherwise gets deleted or aged out of internet sources. Just one symptom of this is that at least 1/3rd of all youtube videos get removed over time, as shown by the number of dead links. (However, to make pages more readable, admins do remove dead links from time to time).
Another aspect of this problem is the purging of hostile comments, and re-editing of own comments, as performed recently by the BBC in the #notmyskin issue over a white campaigner self-identifying as black.
I just came across another aspect of the information loss. I was tracing back thru some of my archived comments, and one very long set on a Youtube video has disappeared; however the video is still there. It seems that I posted a response to one person's comment, but that person has since closed their account. Consequently, their original comment has been deleted, and every single response to their comment, no matter who it was from.
So we all need to be aware that, even with out any dirty tricks, for totally benign reasons, our carefully prepared comments can be totally wiped out.
There is not much to be done.
Organisations (e.g. MCB) have had compromising stuff wiped from www.archive.org.
The only option is to use one of the bookmarking services which also makes one's (personal) archive of the bookmarked page.
If all this is re-writing of history can take place on a sporadic basis, imagine what can happen with a centralised, highly-funded sustained campaign. One can find Thomas Pellow's printed account of being a white slave in the National Archive. But it is almost impossible to find the description of what was done in the process of torturing Kris Donald to death.
All it takes is for a hostile employee at Ning to "accidentally" delete 4F & the backups. Poof...all gone.
Err, excuse me, that was the architecture of last century. If it is possible for a single employee to erase the archive copies now, there is something seriously wrong. But I don't deny that a single rogue admin could delete the current working copy of 4F.
For one thing, the archive copies (I prefer to call this Versioning) may end up at another site, on tapes of some form or other. Obviously it depends how robust the architecture is, but if it is reasonably robust, then to delete all copies including archive copies, would require a sustained effort by a team of people, over several days, and of course, with appropriate sign-off. It's not easy!
Of course 4F is not important to Ning. But the issue is one of generality. Ning should have, and if it is using good Cloud facilities it will have, a structure in place to protect the data of its corporate clients, and that means proper archiving. And if that structure is in place, then the cheapest and easiest thing to do is to plug all the other clients into it, no matter how big or small.
