Your files are removed probably not because of DMCA reasons. Instead they were removed because there are bugs with their systems. A few website owners also have their files deleted eventhough their files were personal and fully legit. I got tired of replacing those thousands of files I re-uploaded numerous times; eventually they will be deleted yet again. My download counts are getting worse everyday because few are willing to download from my Bitshare links. At least they went for Fileserve instead....
