Constant Content

I'm new to Constant Content and having written a lot of articles over the years I'm a little worried that I might duplicate a sentence I've written before. Not intentionally, but purely coincidental. Would this be considered plagiarism? Would someone get in touch with me regarding a duplicated sentence?

well, i understand your frustrations at escaping copyscape. But, Content is a king for every website, article, blogs etc... without content , you cant get enough traffic for your website. But because of my busy schedule i found a good writer that helps me to write quality content for my website shorturl.at/dBNW6. she has been my best writer so far, she is good. i never had problems with plagiarism.
