You lose your followers if you get banned. I was following someone who got banned for disagreeing with moderation policies. I suggested asking the admin to help with the migration; he did, and the admin refused.
This was a rather large server too, featured on JoinMastodon.
Generally all official mastodon servers are very left leaning, so if you are conservative, you might get banned quickly, and certainly the admin won't help you migrate.
