IMHO sony blokuje ty adresy kvuli tomu, ze se z nich nekdo pokousi zneuzit/ukrast nejake playstationove ucty. POkud mate verejne IP registrovane u RIPE spravne tak Vam na abuse email zrejme chodi upozorneni, ze dana IP byla blacklistovana. Takze je potreba vyresit zavirovane/hacknute klienty pripadne open proxy u klientu apod.

It is most likely the attack traffic is directed at one of the following endpoints:
account.sonyentertainmentnetwork.com
auth.np.ac.playstation.net
auth.api.sonyentertainmentnetwork.com
auth.api.np.ac.playstation.net
These endpoints on our network are resolved by Geo DNS, so the IP addresses they resolve to will depend on the originating IP address.
The destination port will be TCP 443.
