If your articles are about well-paying topics then you will have a huge problem trying to protect your site from scrapers. They will copy your articles and post them as their own and maybe even out-rank you in the search engines.
There are plenty of discussions in other forums of this site about such cases but not a lot about how to protect your site. Maybe you should hire a security expert to help set up a protection system.
Publish a few articles then wait a few weeks to see what happens.
