Right now I just tried to make a manual post in one wordpress blog, but after making the comment, the page just reloaded, and no action was taken, so then I replaced my website link with another one and then it was approved/under moderation. I tried this in about 10 wordpress blogs, including my own wordpress blog which occurred the same. Is the link of my site in a spam blacklist? Anyone here experienced the same issue? How can this be reverted?
