I’ve installed the Ban Hammer plugin to WordPress, which lets me block user account creations from spammers, based entirely on their domain name. They used a fairly predictable set of domains to start with, and I also use the Restrict User Access plugin, which lets me block new subscribers from writing posts and comments, until their content is approved at least once. So far, only a couple people have posted besides the spammers. Nearly zero accounts are sophisticated enough to respond to the wordpress email verfication message, but they are getting smarter at building virtual personalities. I don’t doubt the Internet content producers will soon consist of 95% from fake sources, the rest being reposts using different titles.
