I have vouched a couple (~3-5) benign comments a while back and now I no longer have a vouch button for comments.

I don't know if the vouch threshold has increased or if the mods have removed my ability to vouch for other comments entirely.

Wondering if it was my good faith attempt to inform a user of their comments being auto-flagged [1] before I had any context that they were supposed to be persona non grata.

I can still vouch submissions though
