Why? Have you told them this? What other info do you gather on them? Do you try to match up their user names with the real names on checks received though the mail? Do you keep track of their mailing addresses? What do you do (or plan to do) with this information? Do the people who join your ping lists know that this investigation is part of the bargain? That's creepy.
I was simply trying to not appear that I was ragging on someone who is, in fact a monthly donor. I don't have any idea how to do computer spying, Nick names are secure and not traceable to personal bank accounts, anyway.
Also I have nothing to do with this website. I just don't want to see it strained to the point of disruption.
