As a user, my advice:
Ignore the quarantine in regards to updates. Just do whatever you would normally do.
Put up a link from your patreon to your Itch. ( I mean, Itch even quarantines the link from Itch to Patreon. It is laughable)
Temporary put up some disclaimer, (or something in the comment section), how your games are currently quarantined and this should clear up shortly, and if people are suspicous they should google your games and follow the official links (which are patreon and itch).
As you might have noticed I saw a lot of bad things. So, how to recognise if something is bad? Do what I just wrote. Follow the official links. Your Patreon does not link to your Itch. This is very suspicous. I could not say, if it is an impostor account or not by that alone. I also saw no link to your public/demo versions on your patreon on the quick. If they are there, I did miss them. So I could also not check, if your archives look the same as on Itch. If I could verify that it is not a fake account, but the real deal, there is a only a small remaining risk that either your account was hacked or your development machine was infected by a virus, thus infecting the files you upload. And for your information, I saw malware that did not even trigger any scanners on virustotal. And lots of legit games that do trigger false positives there.
