Regulatory SPAM

The Washington Post has an interesting piece about the huge volume of "SPAM" comments that the FCC received regarding the net neutrality rule. This all seemed very familiar to me:  the CFPB received an enormous number of comments about the payday rule. Many were utter spam comments, but the most problematic would attach random academic articles.  That meant that the Bureau's staff, when analyzing the comments, had to spend time on deliberate wild goose chases. (I'm aware of this because a number of the random articles were my own.) I wasn't sure what to make of the volume of frivolous comments; now I'm wondering if there was a giant spamming of the bureau. Are there legal consequences for such actions? It certainly feels icky, along the lines of inflammatory news stories fed by a foreign government to affect our elections.
