There should be a checkbox to hide the file. I would assume that this ... hides the file.
I do not think you understood what I meant with the linking.
You want consistency. If you link to Patreon, you want to have a link to Itch on Patreon. And if you link to Discord, it is the same. And for every other platform you link to.
And if you want to "hide" the quarantine, you can delete this thread, if you want to.
Itch will not notify you about the ending of quarantine. They did not tell you the game is in quarantine either. This can take longer than a month. Delisting is a side effect of quarantine. So if your game is listed again, the quarantine is also over.
