This is the same as a couple of other posts from a few months ago. I tried to upload and I received the “Aww, Mike Denison (Lumberfork) recently deleted that track” banner. I tried changing the file name, changing the bitrate, uploading from different places and even using VPN. I tried about 10 times. Persistence was not victorious. 
Tried again a few hours later and it seems to have worked this time. Not sure why the spam filter was mad but it’s less angry now.
