You wanted to know what is going on. And what you described did fit previously seen scammer activity. They repeatedly commented on the same games, with new accounts, hourly, daily, for weeks.
feel free to block spam comments
Itch does so. But spammers are trying again and again. Creating a spam filter that does blocks all spam and does not result in false positives, is rather impossible.
You claimed, it would affect games negatively. I disagreed and elaborated why I think so.
what do I honestly care if other people can make comments
Likewise. And developers that shut down comment sections entirely thought so too. Screw comments, protecting users from spam is more important.
If there is no spam anymore they can try improving to get less false positives. They are working on it.

Meanwhile, moderation costs money and commenting does not generate money. The first moderator is the devloper. If the developers do not bother keeping their page moderated, why should Itch bother. The devleoper has ability to delete unwanted comments, so they should fulfill their obligation to allow wanted comments.
Also, there were all sorts of spam. With obfuscated links, images. Links were just the most common one. It is trivial to circumvent a simple link ban and auto-filter.
Free to lock thread
Seems you are another person that thinks this is answered by staff. I complained about this, but no one listens. This is not support. This is a user message board. You are talking to other users. People that bother to voice their opinion, share their experiences and maybe answer questions.
If you want to tell support anything, you need to send a mail. Or use the feedback button. Tell them how great it would be, if they would implement it, so that developers would see pending comments for moderation more easy. Maybe that would help a huge lot.
