Labels on my account

After migrating I now have two labels on my account ("Independent PDS" and "eurosky.social"). Is there an official way to appeal?

These labels come from a third-party labeller (@pds.labeler.tny.im), not from Eurosky. Eurosky has no control over them. They carry no disadvantage - they simply indicate which PDS hosts your account. You can appeal directly via the labeller if you wish.
