"Raise doubts" is a bit stingy. Here is what one of the allegedly-harrassed women had to say (in the Paste article): “These claims that Matt would do this stuff are ridiculous,” she said. “I left The eXile because we started dating, and Matt was worried about impropriety. He didn’t even ask me out at work! Matt is a fundamentally decent and kind person.”

The smear seems to me to have been completely refuted on the facts, and there's a second issue: if it hadn't been, there's no way those mainstream publications would have retracted it en masse (especially not given the social climate around that topic). When was the last time they all did that? It's practically a magic trick to get them to do that.
