beware with eric green aka RYC[dot]com
especially if you have your own blog,
happen to me, their bot are watching my site and make me create another domain and shutdown my main domain with result no deletation files, but when I turn my main domain the deletation starts again
uploading files is hard, but re upload files is harder, as you must edit the posted links
that's why I'm only post by folder link not files link
Did you have backup files on the same account and they delete them too?
I wonder whether it helps if you have multiple backup files on the same account so that when a file gets deleted you just make a copy
