Would you get banned for using scripts on Blogger?

I been expermenting with some niches and took a shot with it with blogger. However, I do want to add the viral lock when visitors will have to like the page to unlock the page. I'm not too sure whether or not I can get banned for this. Do you guys have any insight on this?

Yes you can do it.
Make sure that you have a backup of your blog.

blogger are pretty fast to detect lockers, you decide to risk it or not..
