Not sure why would anyone rename his files, but i'll consider adding MD5 checks later.

Well, I like the filename to be actually meaningful -- much better than '6a7931cc3867dbaced4c032b4af79888', and calculating md5sum only takes a few seconds per 10mb of input, which is completely trivial for 99% of files.

I suppose I should publish my own tool to do this.

BTW, if md5 has changed on the server side, that means that the post you are looking for still exists, as a deleted post (probably with a link to the revised post in the deletion reason.).
