All of your uploads are still available, but shadowbanned (as in, they won't appear in search results). You can spot uploads that have been removed by looking at the upload's thumbnail image on the creator's profile: all fully removed items are missing their thumbnails.
Also, for anyone who is trying to download a removed item, paste its URL into the Itch.io desktop client, or (if it was ever submitted to a game jam) navigate to the jam submission page for that item. Both of those methods still work for downloading fully removed items, at least for now.
