Yeah I get what you're saying, but for example. I joined Steemit in October 2017, but made the first post in January 2017. The three months were just to look around and get the "hang" of the place. I also know quite some people who aren't bloggers or content writers themselves, but those people should also be allowed to share their opinions via comments. Not everyone is great at writing articles. :D
All what I'm saying doesn't have to apply to that particular user which caused this topic atm. I'm just talking looking at the bigger picture.
Of course there is always a slight chance that someone is just trolling with a second account etc, but this shouldn't always be the first assumption. :D Or if it is, ignoring the comment of that account would be better than to jump on it.
