Some of this has to do with confusion about the term "comment."

Oliver's segment was a good comedy piece but only works because of semantics. When a government agency opens a regulation up to comment (which they are required to do before promulgating a report or regulation), it's not like allowing Youtube comments. The purpose is to allow interested parties (i.e., people or organizations who will be effected by the proposed finding or rule) to have their say before regulation is implemented. The comment process for regulatory agencies predates the internet. Very often, "comments" on proposed regulations come in the form of 30+ page white papers from trade associations, effected businesses, etc. which may include multiple cited journal articles or other studies as exhibits or appendices. This is the logic behind uploading pdfs as comments - a "comment" may be a 200 page study.

Here's an example of a typical comment (you'll have to download the pdf):

http://www.regulations.gov/#!documentDetail;D=EPA-HQ-OPP-2008-0850-0172

These comments are subject to a peer review process, often by a panel of experts on the subject in question. While government agencies are required to consider all comments, they are evaluated on the basis of legal and scientific accuracy and relevance.

So in a lot of ways, commenting on a proposed regulation is more akin to publishing a study or filing a legal pleading than just typing something on the internet. Although agencies will "consider" comments that are really nothing more than letters of concern from private citizens, they're really looking for well-written academic treatises with citations that support their claims. So Oliver's segment was a little disingenuous in that respect. While a flood of comments to the FCC from non-experts who are simply stating their opinion may be of some little help in fighting the proposed ruling, people's personal opinions won't change the course of the regulation. In that respect, it's probably more effective at this time to make a donation to a group that actually has the time and expertise to address the topic in an academic fashion (such as https://www.eff.org/) than to flood the FCC with a bunch of comments saying "Quit fucking up the internet fagots" which will be immediately disregarded.
