Ask for login to facebook but I gave them a fake one. But they ask you if you have credit cards and there is no n/a so it won't let you go on.
Simply click the "violates MTurk TOS" link in the bottom right, since it obviously does. If you want to work on these HITs anyway try to find some CC infos for testing purpose. i used them a while ago while testing something for a store. if i find the link i`ll update my post
