To be perfectly honest, it looks more suspicious with Solus giving Varrius a '500m blaze cu'...What's a 500m dog compared to an entire account and house worth of loot? And anyone who knows Varrius, knows he had way more than 500m worth of items.
Also, this looks to be more of a personal attack. Not only did his account get looted dry, but the person/people took the time to delete every single character, on every single shard. So, for me, that tells me that it wasn't some random person.
Two people scorned come to mind for me and being this is the lay it all out thread, while we watch Solus continue denying he had any part in it...Kristen and Solus had motive. Solus had Varrius's main email. Varrius's master EA account was hacked via main email. I do not think Solus has the know-how to hack someone's account by himself, but I do feel he had an emotional breakdown, causing him to have really bad judgment and provided Kristen and possibly others with vital information to hack Varrius.
Sadly, in this world-You get your hands on someones main email to something on the internet, gather some key information, you can do almost anything. Only a select few people could know enough to pull off, 'social engineering', I know Kristen could, especially with help-Solus.
