sad, sad news indeed. my condolences to his family and indeed his friends. I never came into contact, nor admittedly was even aware of his presence on the forum, but death in one so young for something as minor as petty bullying is very upsetting indeed.
Looking at his post history it becomes apparent who one of the mocking forum members the op speaks of was, pray they forgive themselves and hope to not find themselves in such a situation.
RIP
