They do seem to come out of the woodwork quickly. Tbf I remember even before the current war, HN had a lot of Russian users - I'm not entirely surprised they would naturally defend their country, even if they aren't oblivious to what is happening.

On other websitrs those are not real users, but bots. Bots that track each mention of a keyword (nowadays can analyse posts too).

I wonder if Dang has any tools to deal with that.
