Having had a look at the site the fact their FAQ tab shows no content and their TOS include "You agree to grant to HumanSpinner a non-exclusive, royalty-free, worldwide, perpetual license, with the right to sub-license, to reproduce, distribute, transmit, create derivative works of, publicly display and publicly perform any materials and other information (including, without limitation, ideas contained therein for new or improved products and services) you submit to any public areas of the Site (such as bulletin boards, forums and newsgroups) or by e-mail to HumanSpinner by all means and in any media now known or hereafter developed.
