You might want to read the other threads talking about the scam spam comments and discuss there. There are several. Like this one https://itch.io/t/5401726/spamming-with-adult-games-link or this https://itch.io/t/5320326/spam-attacks
Also, your comment section is not your game page. It is the comment section. It is so obviously spam, why should this reflect bad on the developer's reputation. It is Itch's reputation that suffers. Your reputation would only suffer if you are obviously active in comment section but do not delete those comments for days.
There is no ticket closure notification for most tickets. And if what you say was your ticket, they probably sorted it in the suggestion basket. A ticket closed message for some tickets sure would be helpful. Like, suggestion received in this case.
