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.
This is more or less how it worked on Reddit. The admins handled vote spam or abuse, there was absolutely no expectation for moderators to have that information because the admins were dealing with the abuse cases. Moderators only concerned themselves with content and comments, the voting was the heart of how the whole thing works, and therefore only admins could see and affect them. Least privilege, basically.
I think a side effect of this, though, is that it increases the responsibility on admins to only federate with instances that have active and cooperative admins. It increases their responsibilities and demands active monitoring, which isn’t a bad thing, but I worry about how the instances that federates openly by default will continue to operate.
If you have to trust the admins, how do you handle new admins, or increasingly absent ones? What if their standards for what constitutes “harassment” don’t match yours? Does the whole instances get defederated? What if it’s a large instance, where communities will be cut off?
I don’t ask any of this as a way to put down this effort because I very, very much want to see this change, but there’s gonna be hurtles that have to be overcome
Ultimately I think the best solution would need assistance from the devs but I’m lieu of that, we have to make due.
