Perhaps - my own pet theory is it was just some bored guys on 4chan who did it because they could. The thing is, a lot of the bots didn't submit comments directly, which would have required getting keys to submit in bulk and leave a trail. Instead, they filled out forms on the many sites that were set up to take names and submit form letters to the FCC. So some advocacy org might set up a site and get a million comments, half of them might be legit and half might be from a script kiddy running a database of addresses and names through the site, which then submits it to the FCC. The site has no particular incentive to vet the submissions. Knowing the IP address of the entity who sent the message to the FCC is close to useless, in that scenario.
