As a sibling comment noted, someone with sufficient permissions in this repo used the “minimize” function on these comments. This is normally intended for disruptive or off-topic messages, but ultimately it’s up to the owners of the repository how they make use of our moderation tools.

Before I worked here I had no idea how much GitHub invests in platform health. It’s nearly invisible to most users but just like every other part of the internet that draws eyeballs we are under an enormous flood of spam at all times.
IMO It’s a testament to how well the system works that many years after this functionality was introduced this is the first time you encountered it.
