I agree with the comments above wholeheartedly. You are on the best route to a ban for spamming. Don't do it. If you are adding new content regularly, then you will get regular spider visits to index it. If you are not making regular changes, then you have nothing to worry about anyway.
Manual submissions to directories are fine. Some of the minority search engines might need a manual submission ONCE. They will probably find you anyway at some point, but I have found it helpful.
