It shouldn't have just been denied an oral presentation, it should have been caught by the program committee and never reviewed. You can't read 3 sentences of that abstract without knowing that it's garbage.

Presumably someone DID review this and deny it an oral, but didn't follow up with the program committee to make sure it was pulled entirely.

I've never been to a conference which pity accepts papers. CVPR, a IEEE conference on computer vision, has a 25% acceptance rate for posters. I think this paper is quite an embarrassment to IEEE.
