As ones of the comments says, you can go to https://ec.europa.eu/info/law/better-regulation/have-your-sa... and search by "invasive" to see that several responses are the same, some identified as police.
But I don't think that's evidence of a botnet. Seems more likely a conventional letter writing campaign where people are invited to paste the same response. Could easily be within the police,which is dubious, but individual police officers may have the right to respond as individuals.
Yeah, I saw this comment [0] and I'm very confused as to how one concludes there is a botnet in play, let alone by a public institution. Most likely it is an employee in the police, which is totally fine. They're not forbidden to express opinion.

It doesn’t really matter whether it’s a botnet or a coordinated campaign by police officers. The fact that police is interfering with the political process is somewhere between a breakdown of the rule of law, and an attempted coup.
Voting isn’t going to fix stuff like this, that’s for sure.
