Unlike crawlers that periodically scrape content, we receive ActivityPub activities in real-time. Your changes are reflected immediately.
When you publish, we receive it instantly via Create activity
When you delete, we receive Delete activity and remove it immediately
When you edit, we receive Update activity and update our index
When you block us, all your content is deleted from our index
Mention us with "follow" or "unfollow" to control your indexing
We only index users who have not opted out. We check these settings before following and before indexing anything:
User has explicitly enabled the "indexable" option. If the setting is missing or off, we do not index.
Account is not locked (no follow approval required)
Neither the bio nor the profile fields contain nobot, noindex or noarchive, with or without a hashtag
You have complete control. Any of these actions will remove all your content from our index:
We will unfollow you and delete all your indexed content immediately.
You can control your indexing by mentioning us directly:
@HolosDiscover follow
We will send you a follow request (if you consent to indexing)
@HolosDiscover unfollow
We will unfollow you and remove all your content from our index
Commands work in public posts or direct messages.
We don't crawl the web. We discover users organically through the Fediverse network:
We see users through boosts, mentions, and replies from accounts we already follow
We verify the user has indexable=true, is not locked, and has no opt-out marker in their bio or profile fields
We send a standard ActivityPub Follow request — visible in their followers list
Once accepted, we receive their public posts via ActivityPub activities
We respect your privacy. Here's what we never index or store:
