I know storage is cheap and that in the future the tangle will horizontally scale.
But I am thinking about bogus spam and its consequences for storage. I know they would be deleted after a snapshot. But a perma-node would keep a copy which seems senseless to me. Could this be a problem since the spammer could troll the perma-node owner this way (because he has to store his stupid spam). Or would this behaviour be non-existent in the future because abusive spamming will not make economic sense?
