Sping is short for "spam ping", and is related to pings from blogs using trackbacks, called trackback spam. Pings are messages sent from blog and publishing tools to a centralized network service providing notification of newly published posts or content. Spings, or ping spam, are pings that are sent from spam blogs, or are sometimes multiple pings in a short interval from a legitimate source, often tens or hundreds per minute, due to misconfigured software, or a wish to make the content coming from the source appear fresh.
