After scraping a huge list and posting manually to the high PR blogs, I'm finding tons of sites that just hang when I hit the submit button. It goes to a white screen on the wp-comments-post.php page. Nothing goes up and it doesn't toss me back into the blog. When I refresh the original URL nothing has been posted. It's not doing this for all the blogs, just about half. Am I getting blocked from Akismet? I've tried swapping proxies, emails, etc. Is it something I'm doing or is the blog just not working properly? What does it look like when someone gets their posts blocked from Akismet? I haven't been hammering that many posts up till now.
