I personnaly find very strange that Elsa/Sahra/Hashie(Official), that have been hiding constantly her identity, suddendly throw an email like that linked to various sites, activities and logs...
It seems to me that it could be a good diversion...
Most likely you find it strange because you´re a sane person trying to apply sanity to the actions of amoral fuckers that should either be behind bars or on the bottom of a lake.
Yeah, but if I just jacked money from people the first thing I would do would be to talk about my other attacks and gloat about it. The person has a high ego to feed and wants to be treated like royalty. They still want to have some control over how this plays out as they control the website and will want to make sure people keep investing.
