We had a really interesting discussion yesterday about voting on Lemmy/PieFed/Mbin and whether they should be private or not, whether they are already public and to what degree, if another way was possible. There was a widely held belief that votes should be private yet it was repeatedly pointed out that a quick visit to an Mbin instance was enough to see all the upvotes and that Lemmy admins already have a quick and easy UI for upvotes and downvotes (with predictable results ). Some thought that using ActivityPub automatically means any privacy is impossible (spoiler: it doesn't).

As a response, I’m trying this out: PieFed accounts now have two profiles within them - one used for posting content and another (with no name, profile photo or bio, etc) for voting. PieFed federates content using the main profile most of the time but when sending votes to Mbin and Lemmy it uses the anonymous profile. The anonymous profile cannot be associated with its controlling account by anyone other than your PieFed instance admin(s). There is one and only one anonymous profile per account so it will still be possible to analyze voting patterns for abuse or manipulation.

ActivityPub geeks: the anonymous profile is a separate Actor with a different url. The Activity for the vote has its “actor” field set to the anonymous Actor url instead of the main Actor. PieFed provides all the usual url endpoints, WebFinger, etc for both actors but only provides user-provided PII for the main one.

That’s all it is. Pretty simple, really.

To enable the anonymous profile, go to https://piefed.social/user/settings and tick the ‘Vote privately’ checkbox. If you make a new account now it will have this ticked already.

This will be a bit controversial, for some. I’ll be listening to your feedback and here to answer any questions. Remember this is just an experiment which could be removed if it turns out to make things worse rather than better. I've done my best to think through the implications and side-effects but there could be things I missed. Let's see how it goes.

No but perhaps it should!

PieFed lacks an API, making it an unattractive tool for scripting bots with. I don't think you'll see any PieFed-based attacks anytime soon.

Do you really think it would matter to a malicious botter if they have a documented API or simply look at the requests the browser makes?

If the pseudo account is banned for it's vote choices, does that really address the issue of vote-banning?

What about PieFed-based shitty humans?

PieFed tracks the percentage of downvotes vs upvotes (calling it "Attitude" in the code and admin UI ), making it easy to spot people who downvote excessively and easy to write functionality that deals with them. Perhaps anonymous voting should only be available to accounts with a normal attitude (within a reasonable tolerance).

I was wondering what attitude was, but I never got around to checking it out in the documentation. I was wondering why PieFed insisted my attitude wasn't 100%. Makes sense now - I guess it just isn't!

(maybe a clickable question mark next to the attitude score explaining briefly what it is could be useful at some point)

Wow your documentation is so much better than ours.

[–] [email protected] 10 points 4 months ago

That's nice of you to say. I've tried to focus well on certain areas that seem important but I really admire the breadth of https://join-lemmy.org/docs/ which I could never hope to cover.
