This means that no content provider should be able to, for example, charge more for faster access to certain data.
One expert described bot activity as a new form of protest.
“Someone has gone out of their way to make these seem like real submissions,” wrote Chris Sinchok in a blog post about the apparently automated activity.
Having downloaded the comments and associated data, Mr Sinchok noticed that the names and email addresses associated with thousands of them also turned up in lists of personal data stolen from websites.
Using ‘breached data’
He told the BBC that this suggested someone might be using information collected from breached databases to make the submissions look more authentic.
“It really seems like this is getting pooled from some place in an automated fashion and it’s coming in at unreasonable rates,” he said.
He added that the uniformity of the data was also a possible giveaway.
For example, many comments are essentially identical save for the occasional, small difference – such as the exact same sentence appearing in multiple comments, but with different letters capitalised each time.
And the rate at which comments were posted also seemed suspicious, starting and stopping in bursts, he added.
