The FCC's comment system was supposed to use a verification process that would confirm users' email addresses were legitimate. However, Pew's research could only confirm that just three percent of comments were validated in this way. Around 57 percent of comments used temporary email addresses or an email address linked to at least one other comment and in many cases, comment submissions listed fake email addresses. For instance, example@example.com was used over 7,500 times and over 9,100 email addresses didn't include the "@" sign. Ten percent of comments didn't even have an email address listed. Additionally, thousands of comments weren't registered to legitimate names. The number one most common name, Pew found, was "Net Neutrality," followed by "The Internet" and "Pat M."

The report also notes that only six percent of comments were unique. Of the other 94 percent, many came from form posts provided by websites like battleforthenet.com and groups like Taxpayers Protection Alliance. However, others appeared to be generated by automated processes, like bot campaigns. On over 100 occasions, 25,000 or more comments were submitted at the exact same time and on nine occasions, 75,000 or more submissions were registered simultaneously. The biggest instance of this saw over 475,000 comments submitted at the exact same second.

Further, aside from pro- or anti-net neutrality comments -- wherever they originated from -- there were also a few very off-topic comments. A few dozen referenced Bee Movie, some even contained parts of the movie's script. Over 100 were made up of mostly non-alphanumeric characters. And others featured short messages like "cat videos," "google it," "SAD!" and "!!!!!!!!!!!!!!!!!!!!!!!!!"

Others have looked into the makeup of these comments as well. Data scientist Jeff Kao recently released his own study that found at least 1.3 million anti-net neutrality comments registered with the FCC were fake and came from a single central source. He also found that just 800,000 of the 22 million total comments were likely to be original and that 99 percent of them supported net neutrality.

"The Center's analysis of these submissions finds that the comments present challenges to anyone hoping to understand the attitudes of the concerned public regarding net neutrality," the Pew Research Center concludes. "It also highlights the ways in which individuals and groups are using modern digital tools to engage in the long-standing practice of speaking out in order to influence government policy decisions."
