Who are you following with a label? Are they honestly being spammy? Check their account and look at their recents casts. Use my guide to help your decide. Please remember this is guidance, not gospel. The spam algorithm is secret, as it should be, so this is based on behavioral patterns of accounts that get marked as spammy.
If you 1000% believe some of the people you follow that have a "0" label are incorrect and you are willing to stake your reputation on it, please plead your case to the Warpcast team on the cast linked below.
Who you follow is important. Unfollow spammy accounts. Save your friends who are mislabeled. Their Warpcast experience is awful.
Level 0 is not eligible for Warpcast rewards. When they tag people, those who were tagged don't get notified. Their replies are sent to the "Show More Replies" bucket. They are basically invisible on Warpcast. Daily Active Users is too small to lose good casters. The algorithm isn't perfect, so we have to help bring attention to those who get caught in the net.
