If not invasions, could anyone speak toward, perhaps, migrations, forays, or exploration into Scandinavia from outside, even Russia?

This is so disappointing that this sub always has interesting topics where virtually everything has been removed by the mods. I wish it were more like a class in which there could be a class discussion where non academics and academics could actually converse. Obviously this sub is already dead with no answers left whatsoever, even though plenty of people contributed. The mods will ruin this sub and soon enough I will be unsubscribing. Coming across topics like this is just so depressing and someone among the mods should discuss this amongst themselves. If only one mod can do this, it seems like a lot of power for one person to wield. Is there any balance of power among the mods?
