sure but how is letting them on twitter helping with that, are there fewer russian trolls on twitter? These dedicated sites are literally 100% concentrated insight into these communities
Authorities in particular, I'm supposed to believe the folks at Homeland Security can't go to Parler and do some open-source intelligence and we need to let the trolls on Facebook instead? It's not like we accidentally pushed the perps into the scary darknet and need the IT guys from CSI, they were literally announcing this stunt proudly to the world, I just don't follow the argument at all.
In fact if the riot hadn't been successful I'd have said Parler is a honeypot because people registering with their ID posting openly that they're starting an insurrection is just too absurd.
