How recent? As recently as last weekend I was seeing blue check marks replying with AI generated only-technically-related replies on top of the majority of the posts I looked at.

There are bots here too, lot of them, to a point that rules were amended, this is because it's very valuable to give points to new publications

If that's actually true, good for them, but after what I've witnessed there not that long ago, I doubt I'll try it ever again.
