Bad bots inflate the usage statistics for sites on the Internet. When page views, clicks, and Likes are the currency, bad bots are false positives.

Not all bots are bad. The ethical ones scour the Internet for new content but identify themselves so as not to interfere with the metrics.

That being said, Internet analytics packages do not seem to pursue spam bots and other ghost referrers aggressively. It is rather like the Federal Communications Commission’s lame response to telemarketers and phone scammers. One imagines the technology exists to hunt down and shut down these malfeasors down, yet they persist.
