Agreed, using a third party service when you know you are going to be subject to scrutiny from those in power is just dumb... but then I've come to expect that from WikiLeaks.
When I was in school long ago I found that from time to time a teacher might try to punish me for my attitude or behavior but not by lowering a value in such a way (if there was such a column on the report card), but by arbitrarily claiming I got 20% less on a given test than I really did scored. Once I discovered this occasional pattern I started to keep rather good records and not giving them an official reason on paper to punish me. Only once did this fail when I was so busy dealing with the demonstrable harassment of the professor that they gave me the lowest grade they could without garnering suspicion (though probably due to me he will likely never teach a college class again)
Julian Assuage would have been better off long ago if he married someone and put on a good enough show of being a committed husband, so much so that any allegations of rape or infidelity would seem like utter nonsense. Yes, some will say that the accusations were/are nonsense, but not weighed in comparison to who he is and presenters himself as a person they seem at a minimum plausible to the common person.
