Actually I am interested to see if the contract will be hacked or not in the future, if not, it might be a good model of how to implement such of functionalities, there is quite of work into the programming actually. After reading the source code I was feeling confident that there is not backdoor and scam exit functions implemented but I wished they did not expose the public account<->transfer token function (thought there will be dividend distributed also here if token are hacked LOL), kind of not really necessary unless you want to be hard to track...
