The goal when ddos'ing nodes is to first set up many nodes yourself, then ddos the other nodes, so you can then have a control of big enough percentage of the nodes so you can spy the transactions with good enough success.

Again, since transactions are fragmented into small pieces and then sent through the network, this attack would not be effective. The attacker could try to spy the network, but the truth of the matter is that the remaining good nodes are still going to end up handling the transactions, however few they may be. But again, since every single wallet is a node, I just don't see this attack being feasible.

How can you tell which nodes are good and which nodes are spying? You can't.

You can't spy productively on XC nodes because private transactions are fragmented and because every node forwards them trustless. This creates a scenario where there's no telling if the sender/recipient of a fragment is the original sender or final recipient, and there's no telling whether the amount sent is the whole amount.

Furthermore since fragments can be sent, even non-private transactions become "private" in this respect, since the amount sent could be a fragment, and so a spy has no grounds to assert that the amount sent/received is the total amount, or that the sender/recipient is the original sender/final recipient.
