Im going through the same issue now. I originally paid my website developer to upload my games but saw that she did a tragic job then went to fix. Soon as I did my games went to quarantine. I've sent two emails to customer support.
Connecting your account from two different computers might have triggerd this. On a glance that might look like a hacked account. Plus there was a lot of uploads on your account.
Practically no one will search your games if you are not famous elsewhere. And at that elsewhere you can distribute a direct link, no searching needed.
The quarantine is of course annoying, but it will go away.
And while Itch might help developers more, it also might protect users more. There do be hacked accounts. I saw several hundred of those this year. You do not have to pay 100 $ upfront to publish, like on Steam. This alone protects against a lot of spam and scam. But it also gives a huge budget to check against any hacking and to expedite any manual checking. Unfortunately, there is no premium service available on Itch you could pay for, so response time of support can take several weeks. They also have to deal with real scams that also got quarantined. Oh, and they probaly will not answer at all, just put your stuff out of quarantine.
If it gets indexed is the next question. You already were unhappy about the uploading, so maybe some of those project pages are not up to indexing standards https://itch.io/docs/creators/quality-guidelines
I glanced over your projects. This here is just a video. It violates categorisation as a game and is basically tag spamming. And the descriptions of all the games I glanced over read AI made, which might indicate shovelware. It is possible, that several of your games were reported for miscategorisation, tag spamming, regular spamming or other things. Which might have triggered quarantine.
Itchi Io still needs to contact the developer.
Why? From their perspecitve, the account might be a scam or hacked. It was accessed from two different continents and suddenly all the projects got changed from the second log in. Should they just ask the account: "hey, you a scammer? please be honest".
In practical terms, there is a waiting queue for support and those manual inspections. Writing more than one mail will not hasten it.
Yeah it sucks as a publishing start, my sympathies, but I also saw hundreds of actually hacked accounts. So I approve of automatics that try to protect users. (If it even was because of this. It really is possible that someone saw your AI generated texts and the mass upload and reported them, because it looked like some shovelware or even stolen from your website.)
None of the games are classified as videos
I think there is a misunderstanding. The project I linked has a single file that ends in .mp4 yet it is classified as a game. Itch does not have a video classification. It would fall under everything else.
