Just a quick note here that I have been using
90DNS and no other traffic blocking plugin (like incognito) since its release, with a clean SysNAND/Pirate CFW EmuNAND dualboot setup thru Hekate. I have had no issues on my OFW SysNAND which I use for multiplayer Pokemon and other games via NSO, and have remained unbanned despite going online often with my EmuNAND for ftp access and unofficial multiplayer.
Going forward, now that I've updated to the latest Atmosphere, I will be adding Exosphere on my EmuNAND as an extra layer of protection (no reason not to).
But let this stand as testament that AveSatanas was legit, despite the weird hate from the SX fanboys.
