I do not think support answers such requests. How would that work? From Itch's perspective at worst case your devloper machine including your account and mail was hacked and taken over. So any request from you could be a scammer talking. And yes, at one time, such a scammer made such a thread here in community asking to be indexed. But I think it was a fake account at that time and not a hacked one.
That they take so long is frustrating. But that they quarantine games with a trigger sensitive automatic is actually good. Not for you and other false positives. But there are indexed malware projects every day. In fact that automatic is not sensitive enough. Or it is, and the actual number of daily malware is a lot higher than estimated - I only see the indexed ones, and those are far too many.
Maybe a scammer is sharing your IP range. Maybe your rpg maker version has false positives when scanned. Maybe there are many reports against your projects from people uncertain if you are an impostor, because of the other account with almost the same name. Maybe your behaviour when updating matches that of a known scammer.
The thing is, this is not possible:
All I ask is that my games stop being put in quarantine unless there are real reasons to suspect they might be fake, contain a virus, or something similar
The reasons are real. You just do not know them. They are not verified. Hence the quarantine and not a suspension. For them to recognise fakes/viruses and so on better, they would need to be able to recognise them better, as silly as its sounds. But the feedback loop of the criminals is very short. They immediatly know, if their method does no longer work and switch to new methods.
This is speculation: since you were not told by Itch that your games are in quarantine and they were probably put there by an automatic, you should ignore the quarantine and update your games as you would do normally and have done so in the past. It does claim to be "due to potential suspicious behavior from the page owner". Tiptoeing and waiting to get indexed and then updating again would sound suspicious to me. So if you do as you normally do, that automatic might recognise this. Or not. I do not know how good or bad the automatic is, I only see a lot of indexed actual malware projects and a lot of devs complaining about not being indexed or having games in quarantine. It is symptoms of a fight against malware uploaders.
