I would agree with goodroi that there is loss over multiple 301s. But I'm confident that the loss over 2 redirects is not 100% of link value.
My point generally was that this loss would seem unlikely to trigger an anti-spam algo, although I suppose it's possible. Regardless, hope this fixes the problems!
