Now that's odd right? Account created in 2019 and not a single comment until now. The comment is also just a quick rebuttal with no substance, the type of comment made by someone who you'd think would comment often.

People who manipulate opinions for some group, country, or company on social media keep accounts stored so when needed they can perform their job.

Or, this person read hackernews for 3 years and never commented (ignoring deleted comments) until just now and only to basically say "no".
