Some artificial creatures display herd behaviour by looking at the way a digital botnet works to attack a network. In DDOS attacks, a person with malicious intents is able to overload a network by herding a large amount of traffic towards it. This traffic consists of actual computers that are trying to connect to the network. If the attacker manages to herd enough traffic to the network, it may need to shut down in order to prevent overloading. 

So-called webscrapers can be seen as creatures that are focussed on gathering data. Whether the goal for this data is to index information on a certain topic, or to find sensitive data to exploit, the behaviour still the same. However, there are some unspoken rules on the internet to prevent these webscrapers from finding data they are not supposed to find. The most common warning sign that website owners can put up to prevent webscrapers from accessing their data is the "robots.txt" file. This file is usually available on every website and tells webscrapers which parts of a website the scraper is allowed to enter. While, some webscrapers might honor this request, there is nothing that might stop a scraper from doing so.

The last example of artificial creatures (maybe unintentionally) showing herd behaviour are smart phones in traffic. A phone by itsefl may not seem like a measurement of traffic. But if you are able to track them on a large scale, companies like Google or Apple may be able to predict the waves of traffic around the world. If a large number of phones have their GPS on, or have their navigation on in some other way, providers of navigational systems are able to predict where there is traffic and where it will proceed next.
