Great question — answering as the UphillTech team:
In the U.S., and indeed likely most all countries that take copyright seriously, will recognize copyright at the creation of a work. This is important to recognize. Copyright is automatic. It is recommended that you remove all work you did not create yourself or created for you. If you only have 7, then remove them immediately. One DMCA complaint, especially one that is resolved without issue or hesitation, will not hurt your site. However, 7 might. Google does not want a site that appears to be low quality and content theft has a long standing history as a significant trigger for spam and low quality sites. Do not wait or take a chance. Act now to remove these 7 pages and you will be okay....
