I think I've just worked it out -- Eric is involved with at least TWO groups.
There's the one that he's doing the keylogger transfer for, and there's the group that he set up the porn site with. That's why he was able to do both things without someone telling him to stop.
I'm not sure which group the good Reverend Thaddeus belongs to, but I'm guessing he's either part of the former, or he's in a THIRD group. The keylogger group is the most likely, as having Eric being involved with three different groups is unlikely, especially at his age.
If this is right, then the second group may not be criminal. If Eric lied and told them that Chris and Steve are over 18, then it becomes a legitimate business venture, even if it is one that is morally questionable. The people he is working with may not know that Eric was doing it without permission.
As for background, I'm guessing that he made contact with the keylogger group during one of his interactions with juvenile hall.
