Ghost Market manipulation

Okay, I'm going to blog about something I've noticed which I think may be an exploit....

I believe that one of my corp members has quit playing. His account appears inactive as the API key says Account disabled due to account status. So this probably means his account has expired....

Interestingly none of his corporate sell orders have expired (don't know about his personal ones) and have been being actioned the past few days, still feeding money to the corp wallet.... So I present Ghost Market Manipulation. Is this an exploit? Do you think its worth a bug report?

If this is true, I wonder how much this has to do with the current huge falls in price of Tritanium and some market side effects - after all, isn't it almost 3 months since the ban-hammer fell on bot accounts - so some 90 day sell/buy orders will be expiring. I've noticed huge falls recently in the price of Trit and even Mex in the short term. I wonder just how much the bot-accounts had on the market when the ban-hammer fell - and whether the lack of bots will be felt more widely than first thought starting now?

What do you think, exploit, or by design? Should CCP fix - as with ghost training being eliminated, surely this is the same thing?
