I created a new site with a wordpress theme , just to check how the articles will appear when adding them in different site sections, I added the test articles that are already was in the theme before uploading it , the content is something like that

"rwkjl weklrjw welkrjwelk werlkjewl "

I added about 10 articles and they're in the site for about 20 days til now because I didn't add the real original content yet ........will this has bad effect on me with google ?,I'm not talking about the ranking , sure it will not rank because there are no real words in it ......but the problem is that I'm afraid that this will make google penalize me ........because I discovered that the site has 90% or more plagiarism using copyscape .......
so

will this make google penalize me ?
Is it too late to delete all these no meaning articles ?
if i add the original content then , will this remove any bad effects caused by the no meaning articles ?

thanks.........I really need help because it's my first site to make
