Searches forum posts for HIT links, follows them, determines if the HIT is still available, and strikes the post if the HIT is ghost or changes the link text to show the automatic approval time and number of remaining if the HIT is available. Using this script will increase the number of page requests you make to mturk and may cause "maximum allowed page request rate" errors.
