Checking who posted would reveal without doubts the spammy nature of the commentor.
But the circumstance is highly dubious to begin with. Someone posts under a game that "a new version" is available somewhere else. Yeah. And the first 100 downloaders will get a coupon.
So I doubt your "most users" statement. Especially if that user is not visiting Itch for the first time. These comments have been going on for several years. A few years ago they would link to internal pages on Itch where a fake game would contain malware. Often with a fake download button. It got better for a while, but the spamming resurged some time ago.
I see three issues here.
You ticket was not a thing for support. You ask for a feature they do not have, so it is a suggestion and not something they could help you with. Also, the underlying issue is the spam comments and that's happening to whole of Itch.
Support did not answer.
You posted about this in the message boards. The rules of this message board include this: Please do not create topics asking how long it will take for support to reply to you.
So your topic was closed, because such topics are not wanted in the discussion boards. You were advised to do discussion about the underlying issue. And I guess your initial ticket was misunderstood, if I take your wording from your OP here. You phrased in this thread: to block hyperlinks on our game's page. Which is nonsensical and is a html problem if you copy paste your page and do not want to have links in there. You are on your own how to design your page. - But what you really wanted is to block links in comments.
Itch sure could handle non actionable support request in a way that people know it is not something support can handle. I think I got a response once, when I reported a bug.
(oh, and your comment section really is a different page. It is just displayed under a game's page for convenience. It is /community or /comments after the game's url.)
