flood the zone

What does "flood the zone" mean here?

“If lots of users share the same post or click on the same link—and if key “influencers” with large personal networks do as well—then it’s more likely to pop up on your screen. To manipulate this process, the Russians “flooded the zone” with a vast network of fake Twitter and Facebook accounts, some carefully designed to appear like American swing voters.”
