I easily saw over 500 hundred malware pages last year in a few months. Most of those on hacked accounts.
What you see happening is Itch doing something about this. That this means delisting and quarantining with a shotgun instead of a scalpel is frustrating for developers. But even a quarantined game can be downloaded. If you have zero promotion happening and only accidental traffic, that is extra frustrating.
But I rather have some developers be delisted for a few weeks and see their complain threads, than see hundreds of hacked accounts spreading more malware.
