There are more, see comment of sneak. A lot of people knew, that he was a "problematic" guy. He was kicked out of a hackerspace in Berlin after he harassed a young girl. The fact that she is still affected by this incident after 10 years shows that this wasn't a minor issue.

Yeah, I saw sneak’s comment afterwards. Despite that being only 2 more people, that was still a far more believable source than this random link.
