well theyve deindexed all my games
That can happen after an update. And just skimming, some of your projects might not be eliglible for indexing according to quality guidelines.

but they never told me why and contacting support doesn't do anything
They never do tell. And they usually never answer indexing requests.
ive just gotten ticket numbers for all my emails
That's not what you wrote. But that's why I asked, because what you wrote seemed implausible.
so it's a deindexed ban but still I'm essentially not on the site. in any case there's no way I can get the game reindexed
You do not know that. I was not joking with the waiting time of over a month. Bigger games than your's get delisted and wait for weeks and weeks.
I looked at some of your project pages. Frankly, indexing them would not do anything. No one is going to search for your game's names and finding them accidentally in tags is not quite possible, since you barely have any tags at all. Your stupid stuff project is not even in the games category. It is "other".
And no they do not need runways, they can hover. Even boards can do that.
