DataDog, I am glad you mentioned that about the victim in this case, a 14 year old boy. He too was disfellowshipped, along with his abuser. Probably for the "practice" of fornication, uncleanness, lewd or brazen conduct, etc.
And you are so right, this despicable action reveals much about the character of the WT cult!!! Blame the victim, punish the victim, abolish him, banish him, obliterate him, don't give him any support, help or counselling.
I think that society still has a double standard about young boys with older women -- a situation often seen as "less bad" or even desirable, than with an older male and young female, say a 30+ year old man with a 14 year old girl.... See? Does the latter sound worse somehow? To me, both situations are abominable. I have worked with children and youths, and though some of the kids can seem pretty "mature", they are not. They are still youths and children! With many insecurities and emotional needs.
In disfelllowshipping the young boy, the WT and its clueless leaders and followers again demonstrate the degree of their "knowledge" and empathy for a sexually abused child or youth who has been taken advantage of sexually. Despicable.
