Private School Labeler on Bluesky. I am utterly delighted by this subversive use of Bluesky's labels feature, which allows you to subscribe to a custom application that then adds visible labels to profiles.

The feature was designed for moderation, but this labeler subverts it by displaying labels on accounts belonging to British public figures showing which expensive private school they went to and what the current fees are for that school.

Here's what it looks like on an account - tapping the label brings up the information about the fees:

These labels are only visible to users who have deliberately subscribed to the labeler. Unsurprisingly, some of those labeled aren't too happy about it!

In response to a comment about attending on a scholarship, the label creator said:

I'm explicit with the labeller that scholarship pupils, grant pupils, etc, are still included - because it's the later effects that are useful context - students from these schools get a leg up and a degree of privilege, which contributes eg to the overrepresentation in British media/politics

On the one hand, there are clearly opportunities for abuse here. But given the opt-in nature of the labelers, this doesn't feel hugely different to someone creating a separate webpage full of information about Bluesky profiles.

I'm intrigued by the possibilities of labelers. There's a list of others on bluesky-labelers.io, including another brilliant hack: Bookmarks, which lets you "report" a post to the labeler and then displays those reported posts in a custom feed - providing a private bookmarks feature that Bluesky itself currently lacks.
