I will investigate the issue with #HolosDiscover. Since another bot was launched on holm.community, I have been getting several complaints:

- NoIndex/nobot in bio not respected
- Locked accounts followed
- AP flag not honored

I contacted the maintainer to ask whether the code was changed. This should never happen. These complaints only started after that bot appeared.

I am taking this very seriously. If the problem is in my code, I will fix it immediately. Sorry about that.


I need help with the server hosting all my open-source projects: #Fedilab, #HolosSocial, #HolosDiscover, and more.
The current server costs €350/year but is no longer suited for the load. I often run out of disk space. I need to migrate to a more powerful one with expandable storage. Renewal is due in a few days.
I have set a goal of €500 on Ko-fi, cost unknown.

Sharing this post helps keep my open-source projects alive.


#HolosDiscover is back, from a clean slate.
A #Fediverse search engine that uses standard #ActivityPub federation. It follows you like any account, respects indexable flags, #nobot, #noindex, locked accounts. Deletions, edits, blocks are processed instantly through ActivityPub.
You have full control. Block it, mention it with "unfollow", or disable indexing in your settings.
Source code under AGPL-3.0 on #Codeberg.

So this dead horse flinched again

"With #HolosDiscover we checked multiple criteria before indexing: "indexable" enabled, account not locked, no #nobot or #noindex in bio, not in opted-out list, only public posts."

I'll copy-pasta with only slight edits:

My entire point (all the noise notwithstanding) focused on

Default opt-in versus default opt-out

This is an agent --> recipient transaction

Default opt-in: the recipient is opted into (and receives) the agent's action whether the recipient --> knows of <-- the action or not

Default opt-out: the recipient is opted out of (and cannot receive) the action whether the recipient --> knows of <-- the action or not

Neither default opt-in nor default opt-out have any logical meaning if

--> THE RECIPIENT DOES NOT KNOW OF THE AGENT <--

in advance

There was no mechanism for prior notification *before* indexing

People would have had to stumble on what you're doing, by how, exactly?

How dose the recipient learn of what you've done *before* you do it?


With #HolosDiscover we checked multiple criteria before indexing: "indexable" enabled, account not locked, no #nobot or #noindex in bio, not in opted-out list, only public posts. Every deletion, edit or block was processed instantly via #ActivityPub.
Google uses that same "indexable" flag but ignores everything else, keeps deleted content cached for weeks.
We shut it down after pushback. Was that the right call? Don't hesitate to share, this concerns the whole Fediverse.

I'm really sad to see this happen. I thought it was a great project that respected users.

We heard you. #HolosDiscover has been shut down, all indexed data deleted, and the source code removed. We apologize for the misunderstanding. Our approach was built with the deepest respect for user consent, but we understand it could rightfully be seen as misusing the indexable flag that many users didn't consciously enable. This highlighted a real conversation the Fediverse needs about default settings. Thank you for the feedback.
