"As anarchists, we must defend ourselves against police and intelligence agencies that conduct targeted digital surveillance for the purposes of incrimination and network mapping." (https://www.anarsec.guide/recommendations/)
I wonder who the anarchists are that are afraid of "incrimination and network mapping" and what it is they're doing them that makes them afraid of that
The point of anarchists is that states are evil. If they want to do something about that, that means the state should be undermined to free it's subjects. That means attacking the state apparatus, which usually sees a very strong response from the security services.
In general one of the defining features of a state is a monopoly on legitimate violence. It stands to reason that challenging a state then involves violence, and sees violence used in retribution.
It's a big leap from thinking there shouldn't be states to undermining them through direct attacks; there aren't many of those, I think. But it is true that security services frequently overstep their boundaries, and that not all countries have proper guarantees during a judicial process, so even innocent anarchists may have something to fear.
