The account is strange, two years old account with barely any comment for two years then a lot of comments in the last 3 days. The 3 first comments of the account capitalise the first letter, everything is lowercase in the last 3 days. He never replies to comments under his own comment. Sadly, a comment of someone who was telling it was a bot account has been flagged ...
On top of that, almost every single recent comment has “—“, that is enough signal in opinion.
