MtGox - Incompetent or Malignant?

I've been having suspicions about MtGox and thinking if their faults are caused by incompetence or malignance. For a company with this income, it is hard to see how they're unable to provide a stable trading platform. Personal profit could be made in orchestrating several "accidents" that would change the market rapidly and therefor enable foresight of events. Right now, every bitcoin in MtGox is trapped for 24-48 hours, not being able to withdraw while Litecoin price surge is happening at other exchanges..

Questions that spring to mind are:
a) Are these accidents coincidence or something else?
b) If this is something else, then what could be done about this? There is no regulation against malignant actions like this in the cryptocurrency exchange system.
c) Should there be more discussions about this subject an about the integrity of the cryptocurrency exchange system?
d) Would information campaigns help? Campaigns that inform newcomers about the trustworthiness of certain exchanges. In this way, cryptocurrency community leaders can regulate the market integrity themselves, without asking for government assistance.
