My application got rejected?

I'm not certain why Postloop rejected me. I think one of the admins deleted my posts. I live in the US, and my rating for the posts are also average, maybe a tad lower. I didn't get the option to re-apply and got the message saying I was rejected. It's sad because some people just copy and paste information from the web, while I make an effort to post. This is the exact same grammar I've been using in my posts. Could anyone point out my grammar mistakes? I think I was rated on one post which I messed up on. The owners should look at all my posts, instead. Could I re-apply? I had an average rating and didn't get the chance to re-apply.
