Of course those employees who got fired by them.
It is a known fact that dismissed employees have a hard time to get over it. The only way to deal with their frustration is working in forums. Actually it is very human. In the case of AAPT there comes to it, that they had to deal with a criminal controller who is now facing court. And as day follows night, this EX has his following and so we have to deal with them as well.
But the good thing to know is, that nobody from those has any stock. How could they pay for? But in beating the stock they are good and we as buyers should actually be thankful to them. We get a chance to buy cheaper.
