X users notice 'PCF_LABEL_NONE' tags under profile pictures, while 'Inferred Interests' list vanishes from settings

X is showing an internal system label called “PCF_LABEL_NONE” under profile pictures across the platform, and it appears to be a bug. Users started flagging it earlier today, with the tag showing up next to usernames in post headers and on profile pages, visible to anyone browsing on the web.

The label is part of X’s PCF system, which stands for Parody, Commentary, and Fan. X has been pushing PCF labels for months now to help users identify accounts that are satirizing or commenting on public figures. “PCF_LABEL_NONE” essentially means the account carries none of those designations, it’s just a regular account. That tag was never supposed to be user-facing, and it’s showing up for a wide range of accounts, verified and not.

Here’s a screenshot shared by a user on X for reference:

The user who shared this noted that the tag appears to show on the web version but may not be visible to the account holder themselves, only to others viewing their profile. Several users in the replies confirmed they couldn’t see the label on their own profiles, while others could clearly see it on theirs.

Apart from just this one thread, reports about the label are flooding in from users around the world.

X hasn’t said anything about it yet. But since it seems like a visual glitch, it’ll likely be resolved sooner rather than later. 

Separately, and also quietly, the “Inferred Interests” list is gone from account settings. The page that used to live at x.com/settings/your_twitter_data/twitter_interests now just returns a dead-end error. Users noticed it missing today, with @ZooL_Smith pointing out that the link simply no longer works.

X now only has something called “Inferred Identity” sitting under off-Twitter activity settings. The two aren’t really the same thing. Inferred Interests was a list of topics X had associated with your account for feed personalization. Inferred Identity is more about how X links your devices, browsers, and email address patterns across sessions to build a profile of who you are.

One user, @MayMayln, pointed this out earlier, noting the settings section had changed. X’s own help documentation describes Inferred Identity as the mechanism by which X figures out that your phone and laptop are the same person, and then uses that to serve you targeted content and ads across both.

Whether the interest list was pulled intentionally or it’s a bug isn’t clear. X hasn’t acknowledged that either, which seems to be a theme for the platform lately. For instance, the platform seems to be killing off the saved searches feature without any official notice. So if features start disappearing out of the blue, don’t be surprised if there’s no official communication about it.

Both issues are drawing attention on the platform right now, though the PCF_LABEL_NONE bug is harder to miss since it’s plastered directly onto posts in the timeline.

We’ll keep an eye out for any further details and will update the article accordingly.
