Over the past week, I've tried comment posting on nearly 10K wordpress blogs, and none of them are appearing when I check the links later on. I don't know what the problem is, because I've taken random blogs that Scrapebox has said its successfully commented, seen that no comment of mine is there, and manually written a comment and then it appears. So it's not because of comment moderation either. I've tried the slow method, same problem. Several show SUCCESS, but upon checking the links, nothing appears. Any ideas?
