What Do We Know About Warpcast Shadowbans?
How to detect a shadowban?

You can’t buy any more warps.
Nobody sees your posts.
Signs that you might have a shadowban:

If you have no power badge, you are more likely to be shadowbanned.
If you can’t buy warps, you probably have a shadowban.
You often post low-quality content ("shitposting") or your account is considered “spammy” (though this is not clearly defined).

If you interact with spammy or shadowbanned accounts, you are more likely to be shadowbanned.
Using a “wrong” IP address can cause a shadowban.
