You are doing women a disservice and possibly much harm.
No. Making unsubstantiated allegations via social media some time after alleged incidents does far more harm. There are facilities in place to make complaints; I believe Abbington began criticizing her teacher on day 3, so not exactly time for a relationship to develop; she made complaints about him to the BBC who did not, apparently, consider them justified so she left, but refused to give reasons. This followed by the drip of innuendo; very difficult to refute.
That is the the sort of behaviour that gives women a bad name; certainly not professional. A concentrated attempt to wreck the career of a fellow professional, albeit one considerably more talented. Dance is a very hard taskmaster and success is hard won.
