Go to wuarchive.wustl.edu

In the uploads area, you can upload a file, download it, etc. but you   
cannot delete it or over write it.

I have seen this on other sites also.  Maybe they are just hacking the   
source.

There's no fool-proof way to do this under UN*X.  Even if we had
separate write and delete permissions, you can always effectively
delete a file by writing an 0-length file on top of it.

Of course, you *do* have the source for ftpd.  Have fun. :-)
