1) Low uptime nodes
2) When a opennet node down for some minutes come back online,
they reseed from the seed nodes and connected to new peers
-- this make the node swap to another location.
Last time we talk about this, we can't decide what to do on mixed
dark/opennet node.
Maybe we can do this just on pure opennet node?
