I feel like this user might have done something other to his system than only using SXOS + XCI. Like (accidentally) going online in a pirated game, install .NSP files, or use homebrew before creating a backup for example. So far the SXOS users that only use it to play XCI and nothing else seem to be safe. I'm including myself here. I've been using SXOS since june, and I have not yet been banned. Only use it to play .XCI, while having my Wifi settings removed, and being in airplane mode. I update my games by removing my SD card, going into OFW, and downloading the latest updates. I do the same for firmware updates. I'm on the latest firmware now, and I'm still good. I've never done a virgin sysnand restore, although I have made one (I just don't like the hassle of restoring my saves).
