A publisher wants to increase the number of users that become loyal and return to the site regularly. Which of the following would NOT help them achieve this goal?

Make it easy for users to connect with them via social networks and then push out their most popular content to drive return visits.
Create a section that links users to popular content on the same subject to drive more engagement.
Give users the option to subscribe to their email list for updates and/or a newsletter.
Prohibit users from viewing the site’s full content unless they visit the site at regular intervals.
Constantly provide new, high-quality content and showcase it on their top landing pages.
