You assume that you and other devs are delisted/quarantined because you did something wrong that you can help. But this is not court, and it is not punishment. If you want an analogy, try airport security.
They will also not tell you how they select people for "random" inspections.
This is done to protect users. And it is very much needed. I saw malware indexed in the hundreds. Not hidden away in password protected files advertised via discord. Malware out in the open on the index. And this is just the stuff I saw. There is bound to be a lot more that I did not see or recognise. And since Itch does not scale with users actions due to a lack of advertisements, they need to do this protection for cheap. So shotgun quarantine it is. Bad for you, my sympathies. But I believe it to be more important to protect users. And your games will get out of quarantine eventually.
My advise for ignoring was meant for your account actions. Maybe the algorithm can recognise this and speed up the quarantine. Actually, outside advertisement is said to speed up all this indexing things. It makes sense. If a lot of people access the page and it turns out to be malware, it would be better to remove it earlier. That you have a hard time advertising your content on sfw sites like youtube is tough for you, but there are more than enough places where you can advertise. And, uhm, people looking for your content do not go looking for it on youtube...
