I logged back onto the site. If it's of any help in tracking them down, the best I understand is that two of the users of the site, "HJ" and "Piton" (which means Python) run the site. You may have already noticed that the downloads (where you enter the username and password) are by the invitation of "HJ".
"Piton" refers to the site as "my site".
On every page a screensaver is listed, they also list directions and a link to their forums, where they distribute registration information for your works and those of all other screensaver and program maker.
These are the forums they have specifically for screensavers:

http://homejungle.ru/cgi-bin/ikonboa...ms.cgi?forum=4
I hope class action could be brought against them.
