That's highly organized. I'm pretty sure you'll find these in many EU countries. Bulk data SIM sales are pretty easy (typically for internet-of-things usage). Let's see if it causes a measurable drop in Russian propaganda online (maybe even here?). This is the information war equivalent of a behind the lines sabotage group and the people involved should be dealt with accordingly: as enemy combatants out of uniform.

The red SIM cards are from COMVIQ, a Swedish telco, the blue ones are for https://prom.ua/ua/p1306199934-sim-karta-sim.html , a Ukrainian telco.

How satisfying it must have been to quite literally pull the plug on this operation.
