Part of the reason they are not banning you yet because of they are making money off you, obviously if you didn't buy any stuffs they probably ban you already, Nintendo does let people get away with using CFW if they buy a lot of content, that it was like on the 3DS. My original post mention about being flagged for a ban, so you probably got flagged for a ban, but they haven't banned you because you purchase stuff.
Then again Nintendo recently implemented a temporary ban, perhaps they got bored of banning people. Atmosphere has no proper protection implementation itself, as it doesn't use any DNS blocker, or edit out your prod.info, 90DNS and Incognito aren't part of the atmosphere.
