I did not find that article compelling. It certainly wasn't of the standard I'd expect for allegations this serious. If that was the first of a three part series, I'd expect they would lead with their best-evidenced material but we have an ex-partner and some anonymous quotes. Plus the claim that there were five co-conspirators dropped in without anything to back it up.
Compare that to the New York Times articles on Harvey Weinstein and the difference in reporting is very stark. In that case, they had multiple people on the record, interviews with people who were told at the time about incidents with Weinstein, and witnesses to events. This is very thin stuff in comparison.
People are entitled to dislike Wootton, to believe he's unethical or a bad journalist but that's a different matter from saying he was involved in blackmailing and catfishing people into sexual acts. I would like to see better evidence than that article before I make my mind up, particularly since Wootton is denying it and appears to be getting lawyers involved.
