FAQ: Why don't I see an account I know?
1. We might not have seen a post from them on the timeline. We are checking the federated timeline every 30 seconds!
2. No one has mentioned that account to us, feel free to @ them at us and our automated system will process them.
3. They do not want to be indexed. Check their profile (on their home instance) for this html:
<meta content='noindex, noarchive' name='robots'>
4. Maybe it is broken? Ask @stefan if the above 3 items seem to not apply
