The only action I could take was if I determined, as herme3 suspected, that it was a staff member here. I can't exactly ban someone else here for an offense on another website, but we may not particularly want to keep a staff member if they are doing something like that. However, it would not be my decision, so I can't really speculate on that.
Also, Section 9 is irrelevant, because I wouldn't be sending data to anybody. herme3 is not going to get a list of several thousand IP addresses to look through. I will look at the address he gives me, determine if it's someone here, and then determine the appropriate course of action from that point. The only people who would know who the person I found was would be the other staff members.
