Can’t this be mitigated decentrally if nodes only accept a limited number of
new connections from a given location per hour - and if opennet nodes which
don’t manage to get accepted just change their location?

With invitations this is useless, even if every invitation only contains a
single darknet noderef which is not online all the time, because that darknet
contact can give you opennet refs.

Ein Mann wird auf der Straße mit einem Messer bedroht.
Zwei Polizisten sind sofort da und halten ein Transparent davor.
"Illegale Szene. Niemand darf das sehen."
Der Mann wird ausgeraubt, erstochen und verblutet,
denn die Polizisten haben beide Hände voll zu tun.
